Bestselling author Suzanne Collins (pictured, via) is writing a new picture book. According to The New York Times, the untitled project will be her “most autobiographical work to date,” using  family members’ names and illustrations inspired by family photos.

This new project will focus on war, a theme present in her two series, The Underland Chronicles and The Hunger Games. Collins’ grandfather, uncle, and father all served in military careers, and the novelist will write about war for teenage audiences.

Collins explained: “I specifically want to do this book, one as a sort of memory piece kind of honoring that year for my family, and two, because I know so many children are experiencing it right now — having deployed parents. And it’s a way I would like to try and communicate my own experience to them.”
