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.

Hey, I live in BANGLADESH. I laughed at the comment in the book, but, still it hurts seeing my country insulted. Anyway, nice book. Not as good as ‘The Fault In Our Stars”, but nice. I liked the math. It helped a lot understanding functions. Thanks for the great read, DO NOT loose the touch.

To me it is a tie between the fault in our stars and abundance of Katherine’s this book was hilarious and down right perfect in every way but, I do have questions mainly about the ending what happens; Do they marry? Or turn around I would really like to this if you have anytime please, fill free to contact me at my current email address:

Hi,
Ive noticed that many would like to know what happens afterwards in your books and id just like to say that i dont. The incomplete endings are my favourite. I love how all your books end, it always makes me wonder what if Hazel died in two weeks or what if there was a car crash in the end of an abundance of katherines or what if Margo decieded to go back home? But i never answer those questions so in my head it ends the way it ends. Hazel reading Augustus sequel, Hassan, Colin and Lindsy driving on an endless rode and Margo and Q just standing there in the dark, i like these never ending, incomplete endings, it makes me happy. Thank you so much for writting such amazing books that have really changed my life and my view on life.

John Green,
I would just like to ask you something. When you were writing An Abundance of Katherine’s, did it ever, perhaps occur to you to spell Katherine a different way? Perhaps, oh I don’t know, Katharine? And also, what is your reasoning for the name Katherine?

Hi John Green! I’m an absolutely fan of yours. The first book that I’ve red is ‘The Fault In Our Stars’ after reading it, I started to love your books and other books! And I know you’re an amazing author, I was inspired by you that’s why I’m writing right now too. I wanted to email you but I do not know your email lol. Right now, I’m writing about my thoughts and feelings and I wanted to share it to you. Hoping one day I’ll see you soon. Keep writing and inspiring us! Lots of love
