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

Dear Mr Green,

I’ve been reading this book for a couple of days now and I can say that you’re such a talented writer. It was like your really from Gutshot and you know how to make unique individuals be as amazing and wonderful in their own special ways. Also, thank you for inspiring a neophyte like me to continue writing my first novel. God bless you!

Sincerely yours,

Hello Mr. Green,

This book was rather dull. I want my money back. Sick Kafir.

No, I’m kidding. It wasn’t too bad. Though it was a bit dull, I did find Hassan absolutely funny and I would ship him with Judge Judy. So yeah. DFTBA.

Dear Mr. Green,
Thank you for all you inspiration with my writing. Seeing you come from the small state of Alabama inspired me to continue with my dream. If you ever happen to see this comment just know you are truly the best author I’ve ever read from. I actually never enjoyed reading until one of my friends recommended “Looking for Alaska” to me, now I’m addicted.
Yours truly,
An inspired reader/writer
