Sometime in 2019, I noticed a new graphic novel in the library that focused on ghosts and…laundry. I was drawn at once into Brenna Thummler‘s enchanting story of loss and friendship, which expanded into a nearly 1,000 page trilogy. When I learned Brenna was following Sheets up with a new tale about mail delivery(!) in the recent but still wild West, I knew I had to learn more:
Me: Congratulations on the release of your new graphic novel GUMSHOE (HarperAlley, Jan. 2026)! Like many, I’ve been waiting for a follow up to your acclaimed Sheets series (one of the recent highlights in all of comics, at least to this fanboy), and Gumshoe did not disappoint. What inspired you to create this book?
Brenna: Thank you! My first intention was to center the story around social anxiety and continue my streak of mental health narratives for kids. As someone who gets nervous in social situations and loves the mail, I thought this combo lent itself to a compelling protagonist. I love weird combos. Sheets grew from the overlap of ghosts and laundry, and Gumshoe was very much my attempt to combine anxiety, mail, and the wild west. It was also important, at the very least for my own enjoyment, that I deviate from the sad tone of the Sheets series. I wanted to create something that was pure joy and adventure. I wanted Gumshoe to be an absurd, vibrant story for kids to get lost in. Sometimes young readers need an escape from the world’s problems just as much as they need to confront them.
Me: Your detailed and evocative settings play a large role in your work. How did you build the convincing world of Stony Lonesome, Arizona?
Brenna: I like my settings to feel real—the narrative hits closer to home that way. In the early stages of Gumshoe, I drove to Arizona with my mom for research and photo reference. I had discovered Bisbee while googling cool wild west towns and knew it would become Stony Lonesome. Bisbee was our first stop, and then we took the Gumshoe Gang’s lead and headed north, hitting tons of quirky towns and landscapes as we made our way towards the Grand Canyon. I have close to 4000 photos and videos from this trip, so truly, any credit to world-building goes to the state of Arizona.
Me: Your books are intricately detailed and colored; and so thick! Can you talk about your process of planning and drawing a book of this scope?
Brenna: For me, the story always dictates the art. I finalize my manuscripts before any visual planning—a “cross that bridge when I get there” sort of process—and it both makes sense and challenges me. It makes sense because I use visuals to fill in the gaps of what the characters can’t say. My rule is this: Words tell the story, but the art tells the truth. It’s challenging, though, to contain my stories within set page limits and not linger on every single emotional high. If I had it my way, Gumshoe would probably be 600 pages long. Editors really help reign their authors in! As for the intricate details, I wish I could simplify, but my brain simply won’t allow it. My illustration style is “intricately-detailed” and boy, is it annoying.
Me: One little Easter egg I have to inquire about: Louis Sacher (the author of Holes, which, hmm, is also a folklore-tinged tale set in the West). Fan mail from Willa?
Brenna: Holes is the greatest middle-grade novel that has ever been penned. It’s also the best book-to-movie adaptation that has ever graced us with its presence. There’s no point in disputing this–you will be wrong.
Me: I love Holes! (my signed Holes happily shares space on my shelf near my signed Sheets trilogy! I like meeting authors, what can I say…)
And speaking of authoring, how did you get into creating graphic novels for young readers?
Brenna: I never planned to become a graphic novelist. I was pretty against it, in fact. Until the end of 2015, I had never even read a graphic novel, and in my ignorance, thought very little of them. And then I was asked to illustrate Anne of Green Gables—a favorite book from childhood—and I couldn’t possibly say “no.” It was during this learning process that I discovered how much I loved graphic novels. Storytelling through sequential art is like solving a puzzle—it’s great brain stimulation. It’s incredibly fulfilling to have to work so hard to get it right, which is why I chose to keep going and write my own.
Me: Can you share what you’re working on next?
Brenna: Yes! I’m working on another graphic novel with HarperAlley. It’s a new story–not at all affiliated with Gumshoe. Again, I started with my love of “weird combos” and found a way to blend croquet, the pursuit of fame in the social media age, and eating disorders. This is my favorite story yet.
Me: Can’t wait! Thank you so much for chatting, Brenna. Wishing your book much success!
