Diego never believed his abuelo’s stories of gods and monsters and the ancient magic woven through Mexican history. Not until he finds himself sprinting down a dark hallway, chased by a beast straight out of lore—its fur as coarse as iron with five human hands clawing furiously at his throat.

Turns out, the myths are real, and their magic is erupting into Diego’s world. As shadowy creatures besiege his apartment, Abuelo’s dog, Cholo, fixes Diego with a human gaze and speaks. Cholo reveals they’ve been unwittingly ensnared in a centuries-old rivalry between the great God Quetzal and his ruthless brother Tezca. Tezca is rising, summoning an army of minions, while Quetzal, the only one strong enough to stop him, has vanished.

Humanity hangs by a thread, and Diego has no choice but to enter Quetzal’s labyrinth—accompanied by Cholo, his friend Violeta, a sassy rubber chicken, and a bloodthirsty kitten—to face a power older than civilization itself. The stakes are legendary, but maybe, deep down, Diego is too.

But when she finally lands on the perfect candidate, it’s in a place she never could have expected — an obituary photo.

Determined to learn more about this dead woman who looks just like her, Gloria embarks on a secret mission to fill in the gaps of her origin story. At first, finding answers about her past feels exactly right. But as the lies Gloria tells keep piling up, and as each step toward her biological family takes her farther from the parents who have loved her forever, she starts to wonder if she’ll ever be able to fill her empty spaces. Because how can you feel truly whole when you’re shattered from the inside out?

Clarisse’s threat was scary enough, but when Katie’s half-brother Grant goes missing, his disappearance sparks the arrival of vicious monsters and a mysterious curse. It’s up to Katie and the three remaining newbies—the Wild Omada—to brave the Wild Zone again and uncover its dark and deadly secrets.

Author Interview with Maire Roche

Author Interview with Maire Roche

Today’s author interview is with Middle Grade author Maire Roche. If you like monsters and retellings, then then buckle up for a fun read! So, without further ado….

KATE: Our Mixed-Up-Files readers would love the inside scoop on your latest book, Little Monsters! Can you tell us a bit about its premise?

MAIRE: Thank you, and I’d love to chat all things Little Monsters! Little Monsters is a monstrous, magical, and modern remix of Little Women, all for a middle grade audience. In this retelling, each of the March sisters is hiding a monstrous power from their foster mom and the world in general. Little Monsters is Meg’s story, as she navigates hiding the sharp claws and twisty teeth that appear when she gets anxious or upset, tries to get everyone Halloween costumes, and develops a crush on the boy next door. Unfortunately for Meg, the closer it gets to Halloween in Salem, the stronger her monstrous magic gets—and she keeps waking up in the woods with no memory of how she got there. She has to learn to rely on her friends and family, accept her magic (and her anxiety), and maybe uncover some spooky secrets about the community she’s living in.

KATE: When I saw the cover of your book and that your story is a retelling of the classic Little Women, I was hooked. Secrets? Monsters? I’m in! As for yourself, what was it about Little Women that pulled you into writing a spooky version of it?

MAIRE: I loved Little Women growing up, but as a kid, I was always drawn to books that had magic and danger. When I was thinking about my childhood reads, I thought about what I would do differently, or what I would add—and right away, adding magic to the March sister’s world made total sense.

KATE: While the classic follows the second sister, Jo, yours follows the eldest sister, Meg. As an older sister, Meg feels a duty to take care of the younger ones. I’m curious what came first for you – the premise (and that’s how you knew to write about Meg) or if you always wanted to give Meg a chance to shine and thus found a story that would fit her?

MAIRE:  I’ve always loved Meg! As a fellow eldest daughter, I always sympathized with Meg’s journey as I read the books. I wanted to translate that to a modern setting, where I wondered what kind of worries an eldest-daughter-Meg would have in today’s world. Of course, in Little Monsters, this version of Meg March isn’t worrying about getting an advantageous marriage that will save her sisters from poverty—but in what way would things like poverty and caring for her sisters still be hers to worry about? I knew I wanted to explore that in my retelling!

KATE: Meg’s friend, John Brooke (aka Brooks) knows a lot about seam cities. I am super intrigued by the idea of these. Can you give readers here a bit of a taste for what a seam city is and why you chose to set Little Monsters in Salem vs one of the other cities?

MAIRE: A seam city is one that sits on the “seam” between worlds. In communities like these, the veil is thin, and the monstrous, mythical, and magical walk side by side with humans. Humans who aren’t part of these magical communities, though, only have vague memories of the monstrous things they see after they leave or move away—or they find other ways to explain away what they saw. But in a seam city,
anything can happen—especially close to Halloween! As far as why I chose Salem, I wanted to choose a city in Massachusetts, since Louisa May Alcott (the author of the original) was from Concord. Salem, as the resident spook city of Massachusetts, seemed like the perfect fit!

KATE: Your story, an absolute fun fantasy to read, also touches on some realistic topics such as the foster care system, first crushes, teenage jobs and responsibilities, and social rumors, to name a few. How were you able to balance these to create such an exciting tale?

MAIRE: First of all, thank you! I’m glad that came through. It was so important to me to write about things kids are really facing. I felt like the other stakes of the story (the monstrous part) wouldn’t mean nearly as much without compelling internal stakes. Meg’s biggest worry isn’t that she’s a monstrous, but that she’s unsure what her family will look like, and who will stay in her life.

KATE: When writing a retelling, how much flexibility is there in creating something new vs using what’s familiar? For example, in Little Monsters we meet familiar characters from the classic such as the four March sisters, yet you’ve definitely added a spin by making them each their own form of monster. If readers wanted to write their own retellings of beloved stories, what tips or advice do you have for them?

MAIRE: I would say don’t worry too much about staying close to the source text! There are so many retellings of our favorite stories (Little Women included) that I think it’s more important to honor the source text where we can, but take liberties wherever and whenever. The point of the retelling is to have fun! You won’t please everyone, and that’s okay—one of the many other retelling will be for them instead. And
you will find some readers that absolutely fall head over heels, which makes it really worth it all.

KATE: It’s often fun to read about the baddies of a book, and in your story we aren’t always sure who the baddie is! How fun was it for you to write an antagonist that keeps the readers guessing?

MAIRE: It was SO much fun. No spoilers, but the antagonist of this story might be my favorite one I’ve written…ever. I find that young readers especially love an interesting villain, and they are my favorite people to write for. They have such interesting questions, and they always seem to take the time to understand all the characters (even the villains). I can’t wait for them to discover this one!

KATE: Without revealing spoilers, can you describe your writing process and, can you give us an example of something you cut, changed, or reworked from draft to publication?

MAIRE: I actually wrote this draft in four days! I wanted to see if I could write something that quickly. Very little changed between that draft and the version we submitted to publishers. After we sold the book, though, I did some reworking of the world building to make sure nothing was too complicated. For instance, I had a whole sequence of scenes in which I’d gotten the phase of the moon wrong. Since the
story relates so much to the full moon on Halloween, I had to rework a lot of that!

KATE: I love that the four sisters have different monster abilities. If I got to transform into one of them, I’d be Beth for sure, since I’d want wings! In Little Monsters we get to witness Meg dealing with what it means for her to be a monster. I’m curious if fans will get to see future books where the other sisters get to showcase their monster sides?

MAIRE: This one I can only say hopefully yes! I have a tentative idea for each sister, each in a different seam city
community, and… we’ll see.

KATE: Thank you for taking the time to share the inside scoop on Little Monsters. Is there something beyond Salem you can hint at? Perhaps a new project in the works?

MAIRE: I am in the process of deciding on my next thing in middle grade right now, so there isn’t much I can say about that genre. However, I do write in a lot of spaces, and I have a really fun follow-up to my cozy romantasy (for grownups) as well as something horror-adjacent I can’t wait to talk about! Stay tuned for some more monstrous middle grade from me, though—I’m definitely eager to stay in this space.

KATE: Where can readers best find you if they want to reach out?

MAIRE: I am online at maryeroach.com or on Instagram @maryeroachauthor. I love to hear from readers, so please reach out, or tag me in a picture of Little Monsters!

Author Interview – Tiffany D. Jackson – Ghosts in the Night

Headshot of Tiffany D. JacksonLast summer, Tiffany D. Jackson published her middle-grade debut Blood in the Water, which became an instant New York Times bestseller, debuting at #4 and has spent a total of 10 weeks on the list. The novel’s success continued this spring when Tiffany received the 2026 Edgar Award for Best Juvenile Book. Now, the “Queen of Thrillers” returns with her sophomore middle-grade mystery—this time set beneath the moss-draped trees of Savannah, Georgia.

 

 

Ghost in the Night Cover with a girl holding a lamp on a haunted street

In GHOST IN THE NIGHT, Jackson transports readers to Savannah, famously known as America’s Most Haunted City, where twelve-year-old Harmony’s fascination with ghosts turns chilling as she’s pulled into a missing-persons case that will expose deadly secrets.

Harmony arrives in Savannah, GA for the summer with her musician father while still dealing with the unresolved emotions around her grandmother’s passing. As they travel from city to city, Harmony insists on one non- negotiable activity everywhere they go: a ghost tour. Desperate to prove that ghosts are real, she hopes evidence of the supernatural will mean her loved ones are never truly gone.

But when the ghost tour in Savannah leads Harmony and her new friends into a dangerous mystery, what begins as a search for spirits quickly becomes something more sinister. The suspicious death of a beloved pillar of Savannah’s Black community, coupled with the disappearance of a young Black boy has everyone on edge. As Harmony digs deeper, she uncovers a tangled web of lies and dark secrets that someone is willing to kill over to keep hidden.

Packed with Jackson’s signature suspenseful storytelling and fast-paced prose, GHOST IN THE NIGHT thoughtfully
explores Savannah’s rich Black history, underscoring everything that unfolds and propels Harmony directly to the center
of the mystery…and the danger.

 

I’ve been on a few ghost tours in the south, and I never grow tired of them. There’s something about the atmosphere and the history! What drew you to include these ghost tours as an inspiration for Ghost in the Night?

TJ: It’s one of my favorite things to do when I visit new cities. Ghost tours give a gritty realistic background. As I always like to say, you can learn a lot from the dead.  

The ghost-hunting tools you mention are top notch!  What kind of research did you do for Ghost in the Night and ghosthunting?

TJ: I went down to Savannah for a week to meet with some experts and do additional ghost tours. I had some pretty spooky/creepy moments. The things I do to write a good book!

I always appreciate it when middle graders are active in solving problems! Tell us a little about Harmony, the main character, and her desires to solve multiple problems in Ghost in the Night?

TJ: Isn’t it fun watching kids solve the world’s problems? They have such a raw unfiltered view, that gives them a clear picture on what they should be looking  for. They’re always eager for information and facts, which makes them a wealth of knowledge.

In your author’s note you mention that you experienced a haunting! Maybe you want to save that story for another time, but I think our readers would love just a couple of details…

TJ: I was in a haunted bar, learning about ghost hunting equipment and while I was chatting, my EMF reader went missing right in front of me. We later found it downstairs. We have no idea how it got there. 

What would you say is the easiest part and the hardest part of writing a mystery?

TJ: The easiest part is coming up with the pitch! The hardest part is landing the pitch, making it believable and satisfying for readers of all ages. 

What are some of your favorite middle grade novels and why do you like them so much? 

TJ: Wait Till Helen Comes was one of my all time favorite books! Of course anything RL Stine wrote. More recently, I really loved the Track Series by Jason Reynolds and The Last Resort Erin Entrada Kelly. 

Now that this book is out in the world, what are some next steps for you? 

TJ: Coming up with the next book, taking time to interact with readers, maybe read a book just for fun.  

Is there anything else you want to share about Ghost in the Night for our audience of teachers, librarians, and middle grade authors? 

TJ: Even though it says “Ghost” in the title, don’t be fooled. This is definitely a mystery (with a little spooky on the side).
