Adventure Picture Book Writer Needed

The goal of this project is to craft a lively picture-book manuscript that keeps 7- to 9-year-olds turning pages. I already know I want an adventure at the heart of the story, packed with action, surprises, and an uplifting ending that leaves children eager to read it again...
