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. From the "New York Times" bestselling author of "The Fault in Our Stars" and "Looking for Alaska", John Green. John has a huge online presence through his 1.1 million Twitter followers and YouTube channel Vlogbrothers, which has been viewed over 200 million times and has 660,000 subscribers, making it one of the most successful online channels in history.
