A instant bestseller, the widely acclaimed novel "Turtles All the Way Down" is now available in paperback!

"Moving and insightful." - The New York Times
"A tender story about learning to cope with the world when it feels out of control." - People

Sixteen-year-old Aza never intended to pursue the mystery of the elusive billionaire Russell Pickett, but there’s a reward of one hundred thousand dollars, and her best and fearless friend Daisy is eager to investigate. Together, they bridge the short distance and the vast differences that separate them from Russell Pickett's son, Davis.

Aza is trying. She’s trying to be a good daughter, a good friend, a good student, and maybe even a good detective, all while living in the ever-tightening spiral of her own thoughts.

In his long-awaited return, John Green, the celebrated, award-winning author of "Looking for Alaska" and "The Fault in Our Stars," tells Aza's story with stunning, unwavering clarity in this brilliant novel about love, resilience, and the power of lifelong friendship.
