An Abundance of Katherines

When it comes to relationships, everyone has a type. Colin Singleton’s type is girls named Katherine. He has dated–and been dumped by–19 Katherines. In the wake of The K-19 Debacle, Colin–an anagram-obsessed washed-up child prodigy–heads out on a road trip with his overweight, Judge Judy- loving friend Hassan. With 10,000 dollars in his pocket and a feral hog on his trail, Colin is on a mission to prove a mathematical theorem he hopes will predict the future of any relationship (and conceivably win the girl).¬†An Abundance of Katherines was a 2007 Michael L. Printz Honor book and a finalist for the Los Angeles Times Book Prize. It was also named one of the books of the year by Booklist, Horn Book, and Kirkus.

Reviews (Spoiler Alert!)

“Imagine an operating room at the start of a daring but well-rehearsed procedure and you will have something of the atmosphere of ”An Abundance of Katherines”: every detail considered, the action unrolling with grace and inevitability.”

-New York Times Book Review

“Green follows his Printz winning Looking for Alaska (2005) with another sharp, intelligent story. The laugh-out-loud humor ranges from delightfully sophomoric to subtly intellectual.”
-Booklist, Starred Review

“Fully fun, challengingly complex, and entirely entertaining.”
-Kirkus, Starred Review

“Laugh-out-loud funny, this second novel by the author of the Printz winner Looking for Alaska charts a singular coming-of-age American road trip that is at once a satire of and a tribute to its many celebrated predecessors.”
-Horn Book, Starred Review

John Green,
I absolutely loved your book An Abundance of Katherines, and I have to say I think it’s my favourite. Many people undermine this book and say that it’s boring but to that, firstly, I would like to say that for me this book was hilarious (Hassan is my spirit animal). Not too many books can make me laugh out loud instead of simply grunting or blowing more air out of my nose than normal, but this one did. Secondly, I could relate to the characters. I haven’t dated a multitude of Katherines or anything, but I related to the ideas of why we exist and what we’re meant to do, and how the future will always be unpredictable, and even the pressure of being looked at as smart and then trying to keep up with that label. By reading this book I guess I sorted a few things out about myself. Clear as mud right?
I just wanted to say thank you for writing such awesome books, you’re truly amazing.

I just have 2 question for Mr. John Green question (1) is how did you get the idea to write this nice book ?

maybe this question is dump but what happens to Hassan?

not only Hassan what happens to everyone. i mean they probably just wouldn’t keep driving. It’s just incomplete still.
