JS: Welcome to the blog. I really loved this book. Let’s start with the first question: What drew you to writing about these two scientists?

Cindy J-E:   In summer 2017, I was driving to my first day at a new full-time teaching job when my agent, Stefanie Sanchez von Borstel, called to give me some updates: a rejection of a manuscript I had recently sent to her, and an opportunity. Cheryl Klein, an editor at Lee and Low Books, was seeking a picture book family biography of Walter and Luis Alvarez, the two scientists behind the discovery of evidence that an asteroid was responsible for the Cretaceous extinction. While I was intrigued – I LOVED my college geology classes and I LOVED teaching science — I was also feeling really overwhelmed. I was making a big career switch from holding five simultaneous but flexible low-paying part-time jobs in high-end communities, to holding one full-time teaching job in a low-income community. I was also switching from teaching grades 1 – 8 science and outdoor education to teaching middle school English to three different grades. As an introvert, full-time teaching has always been challenging for my psyche, especially when my kids were young. So I was especially nervous about the return to the classroom. However, writing, even in my most successful years writing for educational test companies, magazines, newspapers and publishers, has never been enough to pay the bills. But I could feel a spark of curiosity igniting.

I told Stefanie I would read Walter Alvarez’s book, T-Rex and the Crater of Doom, and see if I wanted to write a picture book biography. How long could that take, right? Over the next few months, I read Alvarez’s book before bed and on weekends, and contemplated how I might tackle a biography. By Christmas, I realized that this would have to be much more than a picture book biography. This story, involving everything in science from Paleontology and Earth Science to Astrophysics, was a science mystery much more complex than a simple biography suggested. For children to understand how scientists solved the mystery of the Cretaceous extinction, they would need to know the science that led to the discovery. I began working on a book proposal for a longer middle grade nonfiction book, and we submitted it to Cheryl in early 2018.

 

JS: How did you decide to turn this book from a “normal” biography focusing on the scientists, to a journey of discovery? 

Cindy J-E: By summer, Cheryl had rejected my first proposal — it’s hard to remember why — but she offered to let me rewrite it, along with a sample chapter, if I wanted to make another attempt. I spent the summer and fall of my second year at the school researching and writing a second draft of the proposal. This time around, I structured it as a long-form science mystery, and developed a structure that included elements I knew my students would appreciate — graphic elements, expository elements, narrative family biography and a narrative of science discovery. I would start it with the discovery of dinosaurs and the idea of extinction, and proceed to the discovery of the crater. In the proposal, I included samples of each type of writing – comic script, expository science, science and biographical narrative — as well as a 20-page outline. We turned the proposal in again and waited. Six months later – a contract!

 

JS: Whose idea was it to use graphic novel-like insets to explain the more complex science? (I think this is brilliant, by the way).

Cindy J-E: Thank you! It was my idea to use graphic nonfiction to explain some of the science through graphic narrative, and it came about because by 2019, I had been segued over to teaching science in my school instead of English, possibly because, in my very traditionally-minded school (at that time) I was teaching students to write comic narratives in English class, in addition to essays. Prepping for science teaching, however, is a lot more work than prepping for English class, so I asked my school if I could teach two grades instead of three, and two types of science – 6th grade Earth Science and 8th grade Physical Science – instead of three (Life Science). At this particular school, this was considered part-time teaching – two preps instead of three – and working 7 -2 instead of 7-4. The best way to learn science, for me, is to teach it and to have to write about it. So having my writing and teaching focused on the same topics was helpful. I wrote the book I wanted my students – 98% of whom were English-language learners – to use to learn science, so graphics were a great resource for them.

 

JS: Can you give us a couple of  intriguing fun facts that you learned while writing this book? 

Cindy J-E: Instead of  intriguing facts, I will give you some amazing facts and experiences I had in researching and writing this book.

Intriguing fact #1: I hadn’t realized how recently, in the grand scheme of things, dinosaurs were discovered at all, AND long it took people to realize that extinction was even possible. When there were parts of Earth that were still uncharted by Europeans, folks thought that maybe dinosaurs were hiding out in some deep, dark pocket of Earth.

This also points to my own realization of how often new and alternative hypotheses are ridiculed, often for decades, until enough data comes in. I tried to include a variety of voices and viewpoints with respect.

Intriguing fact #2: When I was scripting the first and last comics, I had written sound effects for the voices of dinosaurs. Then I came across a study by a scientist who studies animal sounds and the acoustics of their skulls. His work suggested that T-Rex probably sounded more like a hunting horn than a roar.

 

JS: What would you like readers to get out of this book?

Cindy J-E: I would like readers to understand the great joy, responsibility and gift science is to our world. As I say at the end, “Scientists – geologists, paleontologists, physicists, and every other researcher in every field – never stop digging for data, collecting evidence and retesting results. The scientific practices of asking questions, tossing around ideas with colleagues from around the world (who often become friends), developing a hypothesis, and testing to see if it is actually true are the eternal pleasures of doing science. Science presents a never-ending opportunity to learn and grow, and to expand the knowledge of civilization. Scientists don’t work for themselves; they work for everyone – everyone on the entire planet, now and in the future – to bring the truth to light and make it accessible and available to the whole world.” (p. 186)

I want readers to understand what the scientific process really is, how it is used, and how our knowledge changes as we gather more information. Science is not static. It is growth.

JS: How would you like teachers/librarians to use this book?

Cindy J-E: I would like this book to be used by teachers who want to collaborate across the curriculum – science and the humanities – as a class book to teaching middle school Earth science curriculum. Students can identify science processes used as the mystery is solved. They can teach students to use comics to explain their ideas.

Five Questions with Kortney Nash, Assistant Editor at Godwin Books

Kortney Nash

Kortney Nash, an assistant editor at Godwin Books/Henry Holt, pops in at From the Mixed-Up Files Of Middle-Grade Authors to share books and advice. She has an inextinguishable love for sci-fi. She was part of the editorial team for the middle-grade graphic novel, Oasis, published February 18, 2025, which has received seven-star reviews so far, as well as a shout-out in the New York Times. As an author, her picture book, Tell Me About Juneteenth, will be released in May 2025.

As a newish editor, tell us about your publishing journey. What types of books did you like to read while growing up and how does that impact the type of list you would like to build?
Growing up, I read all types of books! I think the first books I fell in love with while learning to read independently were the Junie B. Jones series. I remember there being a lot of humor in those, and they really drove home to me that reading can be fun––those books may be the reason I ended up in the publishing industry! That series turned me into an avid reader, and before you knew it I was devouring The Hunger Games, Maze Runner, and pretty much all of the popular titles that dominated the pop culture landscape during my childhood and teenage years.

When I’m at work, I’m always thinking about these titles that nurtured my love of reading and what made them special for me. I found a lot of excitement in the high-octane fast paced series that I previously mentioned, but was also profoundly touched by books like The House On Mango Street and Walk Two Moons––stories that struck a deep chord within me emotionally. When I’m looking for titles to acquire, this is the balance I’m thinking about. I want a bit of everything, something for every reader out there.

Can you talk about what books you’re currently editing and what attracted you to those projects?
I can’t give too many details at this stage, but I most often find myself drawn to projects that center marginalized voices in multifaceted ways. I love stories with BIPOC and/or queer leads where the main characters are having fun or dealing with the paranormal or stepping into fantasy worlds. When I was growing up, most of the books that had Black main characters dealt with racism as a main focal point of the plot––and left a void for Black readers looking for stories that didn’t just focus on the struggles of Black life, but Black joy as well. I like books that achieve this in different ways, they heal my inner child!

What type of book would you love to acquire but haven’t read yet?
This is incredibly specific, but I’ll throw it into the void anyway: I want a sci-fi boarding school murder mystery! I’ve been putting this request out into the universe for a hot minute now, so I think the energy will (hopefully) come back to me soon. There are so many magic school books, but I haven’t seen a ton of sci-fi that drifts into that zone, which hurts my heart as a devoted Star Trek fan. I think there’s a lot of potential to do some fun stuff in that space, and I’ll be ready to acquire it as soon as it hits my inbox.

For those looking to build up their library of diverse reads, what middle-grade books would you recommend?
Oasis by GuojingI love this question! Middle grade is such a unique space in books, and I think that we can all benefit from reading middle-grade novels no matter how old we are. I seriously can’t recommend Oasis enough. The art is beyond stunning, and the story is just so incredibly moving. It’s one of those books that you wish would never end! I was very fortunate to get to watch things come together behind the scenes for that book, so there is some extra special sentimental value for me there, but even from an objective perspective, I think there’s no denying that it’s a really compelling read that brings something fresh to the sci-fi space. I don’t want to spoil anything, but if you’re looking for something dystopian-leaning with themes about family and hope, then this book is for you! If you’re not looking for those things, this book is still for you. In short, read the book no matter who you are, you won’t regret it.

Otherwise, I’m also always recommending Genesis Begins Again by Alicia D. Williams whenever I can because I read it and just really adored it! I found the voice so compelling and appreciated the way the author tackled important issues like colorism and class head-on. I’d also be remiss if I didn’t throw Remy Lai into the mix––I loved the humor and heart in Pie in the Sky and have had Ghost Book on my TBR for a hot minute now! Remy’s art is so fantastic, and she really has a gift for drawing readers in on the very first page.

 

Kwame Crashes the Underworld by Craig Kofi FarmerThere’s also Kwame Crashes the Underworld, a middle-grade fantasy steeped in Ghanaian culture that just won the Coretta Scott King John Steptoe New Talent Award. And to round out my recommendation, I’m going to shout out The Haunted States of America, a middle-grade anthology I edited that features 52 different authors––one from every state in the US as well as DC and Puerto Rico. I could recommend books all day, but I’ll stop there for now!

What advice would you give to others looking for a career in publishing?
For those looking for a career in publishing, I’d recommend reading widely first and foremost! Besides that, pay attention to who published the books you’re reading––if you notice you’re reading a lot of books produced by the same imprint, try seeing if you can have an informational interview with someone who works there to learn more about their approach to book publishing. You only live once, so I would overall say don’t be afraid to reach out to folks (in a respectful way) to ask questions about what the day-to-day looks like in different departments. Everyone I’ve met has entered the industry from a different angle, so I don’t think there’s a one-size-fits-all method for beginning a career in publishing. However, persistence and patience go a long way!

Bonus Question:

If you could swap lives with any character from a novel, who would you choose?
I would swap lives with Mark from Andy Weir’s The Martian. I need some time to chill out on a different planet, even if it means getting stranded:) I would eventually work hard to get back to Earth though! Eventually!
