Aza's life is filled with complications.

Living with anxiety and OCD is enough but when Daisy, her Best and Most Fearless Friend, brings her on a mission to find a fugitive billionaire things are about to get even more complicated.

To find Russell Pickett, Aza must enter the world of his geeky, but maybe kind-of-cute son, Davis.

But the chances of a first kiss, and maybe even a first love, could send Aza into a spiral of anxiety...

A perfect coming-of-age novel filled with love, mystery and Star Wars fan-fiction.

In his long-awaited return John Green, the acclaimed author of the Fault in Our Stars, shares Aza's story with shattering, unflinching clarity in this brilliant novel about mental health, love, resilience, and the power of lifelong friendship.
