From the bestselling author of Turtles All the Way Down and The Fault in Their Stars, a beautiful tale of love, loss and not so fool proof mathematic equations.


When it comes to relationships, Colin Singleton's type is girls named Katherine.

And when it comes to girls named Katherine, Colin is always getting dumped.

Nineteen times, to be exact.

On a road trip miles from home, this anagram-happy, washed-up child prodigy has ten thousand dollars in his pocket, a bloodthirsty feral hog on his trail, and an overweight Judge Judy-loving best friend riding shotgun - but no Katherines.

Colin is on a mission to prove The Theorem of Underlying Katherine Predictability, which he hopes will predict the future of any relationship, avenge Dumpees everywhere, and finally win him the girl.

Love, friendship, and a dead Austro-Hungarian archduke add up to surprising and heart-changing conclusions in this ingeniously layered comic novel about reinventing oneself.
