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.

As someone who enjoys math, fiction, and quirk, this should have been my kind of book, but it wasn’t. The humor mostly worked, and the only relationship that truly invested me was the chemistry between Hassan and Colin. The rest felt like an extremely slow trawl of dying cod through the endless Katherines’ backstories. It was alright overall, though I honestly enjoyed the Appendix more than the actual book.

A rather long disaster, quite like watching a slow car crash.

It was hard to get through at some points because it could be boring and uneventful. But the whole point at the end of the book is good.
