Turtles All the Way Down

John Green

Sixteen-year-old Aza Holmes gets pulled into investigating the disappearance of a fugitive billionaire alongside her best friend Daisy, reconnecting with the missing man's son, Davis, along the way. As the mystery unfolds, the novel focuses less on the case and more on Aza's internal battle with crippling anxiety and OCD, and how that struggle shapes her friendships and budding romantic feelings. It's a quietly powerful, introspective coming-of-age story about living with a mind that often works against you.
