Turtles All the Way Down

by John Green

Sixteen-year-old Aza Holmes has always lived with obsessive-compulsive disorder and the ever-tightening spiral of her own thoughts. When a fugitive billionaire goes missing and a reward is offered for information, she and her best friend Daisy undertake an investigation that leads to unexpected places. Green's most personal novel draws on his own long experience with OCD and intrusive thoughts. Adapted into a 2024 film on Max.
