An Abundance Of Katherines is a young adult novel with a maths-loving protagonist named Colin who wishes to be a good mathematician. Colin Singleton’s type happens to be a girl named Katherine when it comes to relationships. 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 to surprising and heart-changing conclusions in this ingeniously layered comic novel about reinventing oneself.
