You’ve never met anyone exactly like twelve-year-old Sarah Nelson. While her friends obsess over Harry Potter, she spends her time writing letters to Atticus Finch. She collects trouble words in her diary. Her best friend is a plant. And she’s never known her mother, who moved away when Sarah was two.

Since then, Sarah and her dad have moved from one small Texas town to another. Even though Sarah can see every inch of her new neighborhood from her perch on the stump in her yard, it still doesn't feel like home.

But when Sarah launches an investigation into her family’s Big Secret, everything changes. She makes unexpected new friends, and has her first real crush. And instead of a “typical boring Sarah Nelson summer”, this one might just turn out to be extraordinary.
