Welcome to the Back Matter Break Down! Are you a picture book author with back matter in your book? Contact me if you’d like to be interviewed on my blog!
I am so excited to share my first author interview for 2026. Emeline Lee is an author of children’s literature. Her picture books include Bonnie’s Rocket (illus. Alina Chau; Lee & Low Books), a STEM-friendly story set during Apollo 11, and Gwei the Hungry Ghost (illus. Basia Tran; Kokila, an imprint of Penguin Young Readers), a whimsical story inspired by Chinese food and folklore. She studied English literature and environmental sustainability at Columbia University and lives in New Jersey. In her free time, Emeline enjoys hiking in nature, eating hot pot, and crocheting cozy things. Today she’s going to share her back matter journey with her newest book, Gwei the Hungry Ghost. Let’s go!

Book: Gwei the Hungry Ghost
Author: Emeline Lee
Illustrator: Basia Tran
Publisher / Year: Kokila, 2026
Genre: Fiction
Topics: Ghost, Myth, Folktale, Chinese Festival, Food, Sharing
Blurb: Gwei the ghost is absolutely famished, but unlike the other ghosts in the cemetery, he won’t eat just anything. Luckily, it’s Ghost Festival month: the one time a year when ghosts roam the realm of the living. Gwei flutters around the city eating steaming bowls of noodles, hot, hot, HOT chestnuts, and crispy fried fish with chili oil. Yet no matter how much Gwei eats, his hunger won’t go away. As he searches for the perfect meal, he catches someone following him. It’s another hungry little ghost! When he hears her grumbling belly, he reluctantly reaches into his pouch to share. To his surprise, he finally starts to feel full.

What is your book’s word count? What is your back matter word count?
Book word count is 595 words. Back matter word count is 730 words.
Tell us a bit about the inspiration for your story.
The story was inspired by hungry ghosts from Chinese mythology. Hungry ghosts are lost and ravenous spirits who eat and eat but never get full. I felt a lot of sympathy for them and wanted to write a story with a friendlier (and hopeful) interpretation of these ghosts.
I was also excited to feature the Hungry Ghost Festival, which occurs in the seventh lunar month around the end of summer. It’s a time in Chinese culture when people believe the realm of living opens up to visitors from the dead. During this time, people may try to avoid unwanted attention from wandering spirits who can bring bad luck, but also honor their ancestors with offerings of food, incense, and burning fake money.
What was the earliest version of the back matter like?
When I submitted the manuscript to my editor, it actually already included an explanation of the Hungry Ghost Festival, an idea for an illustrated ghost guide, a glossary, and even references—all of which made it into the final after edits and polishing. I think it was helpful to demonstrate my research and knowledge in the subject matter early on.
What kind of research did you do for the back matter?
For the ghost guide, I read additional folktales and Buddhist texts that influenced the Chinese concepts of ghosts. I also found scholarly texts about the history and origins of the Hungry Ghost Festival. But it’s important to note that since folklore varies from region to region and is often passed down orally, there may be multiple definitions or stories to explain a particular aspect of mythology.
Your back matter shows the ghosts names in Chinese characters along with pronunciation guides. What was the process of deciding on what characters and pronunciations to use?
That’s a great question! The Chinese characters are “traditional” (versus simplified), and the pronunciation is what we call “pinyin” or the standard romanization for Mandarin Chinese. Fun fact: Taiwan uses traditional characters, and since my Chinese teachers growing up were Taiwanese, I first learned writing that way! Since I’m still a student of the language, part of the editorial process included a language expert who reviewed the book to ensure accuracy.
I love how the different ghosts are shown in Basia Tran’s illustrations at the beginning of the book, and then again in the back matter. Did you collaborate with Basia on these portrayals?
Basia did a fantastic job creating the look of each ghost (and making them adorable)! I provided her with very broad descriptions, and she did the rest—which wasn’t easy, given that several of them have the ability to shapeshift, and one of them can transform into literal darkness. During the editorial process, I gave occasional feedback to ensure the illustrations honored the traditional folklore while being our own interpretation. Basia sprinkled these other ghosts and spirits throughout the book, so readers can have fun picking them out upon rereading.
Are there any picture books you’d recommend for their back matter?
There are so many I love for different reasons! I’ll just mention my current top five examples with a short explanation:
We Are Water Protectors written by Carole Lindstrom and illustrated by Michaela Goade. This is a great example of creators sharing their personal connection to the story. It’s a special standout for me because it also includes an “Earth Steward and Water Protector Pledge” for readers to sign. I love how the back matter invites and motivates readers into positive climate action.
Up, Up, Ever Up! Junko Tabei: A Life in the Mountains written by Anita Yasuda and illustrated by Yuko Shimizu. Picture book biographies tend to include back matter to elaborate on the subject’s life, and Anita does that and more. She also includes a timeline, glossary, and comprehensive bibliography, which is great for student readers to see how academic research is done and continue learning.
The Night Before Eid written by Aya Khalil and illustrated by Rashin Kheiriyeh. I love when picture books include activities to continue the fun and immerse the readers. In addition to sharing her background alongside family photos, Aya adds a delicious ka’ak recipe.
Jumper by Jessica Lanan. This non-fiction STEM book is a treasure trove of back matter. Jessica includes six whole pages of beautifully illustrated back matter that features facts and diagrams to explain jumping spider anatomy, life cycle, and more.
Whale Fall written by Melissa Stewart and illustrated by Rob Dunlavey. Like Jumper, this STEM book has six pages of back matter that dives deeper into scientific details. With an illustrated species guide, extensive sources, and recommendations for further exploration, this back matter is not to be missed!
Thank you, Emeline! Your back matter shows the importance of collaboration to getting those finer details perfect for publication–but it all started with your preparation and research to set the vision for everyone else. Please support Emeline:
