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

Heyo John!
If you don’t mind, I actually used you as my subject in my Art essay themed: “The Genius of Man”. How can I not when you are truly a genius? I can’t express how much I’m very grateful for your writing but just in case you want to know what my essay contained you can email me and i’ll send it to you.
I love your books and i can’t wait for your upcoming ones. You truly helped in shaping me to be who I am today and I can’t thank you enough. Your books were the source of my heartbreak but it was also the one who gave me my inspiration to write my own story and express my feelings through writing. I’m very honored to witness your genius through your works and through being a nerdfighter. I hope you never stop writing and inspiring not only me but a lot of people across the world.
God Bless,
Trisha

Good day Mr. Green! I’m a big fan from the Philippines. I have watched TFIOS and have read Paper Towns. Those are really great and awesome. I hope one day, you’ll visit our country and got a chance to know more about you. But this time, I’m hoping you’ll read this letter. Your works will be the legacy to the future generation so please don’t stop writing. Thank you for all your inspiring stories about teenagers. I’m a true witness of your greatness. God bless, Zyra

I haven’t read this book yet, but I feel that it seems oddly weird. Why would a guy only be interested in girls named Katherine?

I thought that it was slightly odd as well. In the book, it says that at first Colin, the main character, didn’t mean for it to happen that way, but after a few Katherines he accepted it as fate and only dated girls with that name from then on. I agree that the whole “I only date Katherines” thing” was a bit unnecessary, though.
That’s not to say that I didn’t love the book, though!

” Hi, ”

I’m from Turkey so I dont know englısh a lot but I want to say ı am a big fan of your books. (I actually send this on e-mail But ı cant find yours.) My favorite one is An a Abundance of Katherines. Cause ı think Lindsley looks like me -ı guess I’m taller- ı got big eyes and a long nose. I havent got a problem with it but ı am a little angry to Hasan.

But ı listen indie-rock music so my favorite Katherine is seventeenth. Absolutly I’m not an emo.

I adore the book and Colin. ( Just sayin if you really think like Peter Van Houten, when the books are finish, the carecters dont die. Cause ı always think about them. ‘Whats happen now?’ Or ‘ So, Lindsley and Colin live together forever’ or ‘ Colin must be mine, ı think every thing he say is interesting!’.) He is not perfect (and ı really like that) and ı dont understand why he throw up when Katherine broke up with he. ( Sorry for my english. I must listen the lessons.)

I can talk with you ( or Mr.Green ı dont know, but ı say you.) all day about the books, Colin, the theorem, Katherines and a little bit Augustus. But thats not the point.

Your thoughts are so true for me! About the books (in part eleven), about being important, and the theorem will be so usefull. But we cant see the future. I want to say a lot of things but ı dont remember them now.

Dont stop writing! ( If Colin was real ı will date with him.)

“Hi.”

Dear John Green,

First of all, I would appreciate if this could be a private contact, but since that is not the case, for now I am noname.
While I appreciate your skill as a writer and love most of your books, I was profoundly shocked by how you portrayed a pg (profoundly gifted) child in your book, ‘An Abundance of Katherines’. Being a pg child myself (IQ of 175+) I strongly feel you should have done much more research before making one of your characters have an IQ of 200, as you say.
Colin does not represent any of the attributes (besides having a good memory) of a pg person. I really am upset about your display of a pg person.

Hopefully you will read this and understand.

Thanks,
Noname8595 (if you contact me privately I can give more information)

So one day in early July I found myself stumbling into the library to spend a good hour before I had tennis practice. I had never read a John Green book. I’m not much for young adult novels (I’m more into science fiction) but I went to the section anyways to read A Fault in Our Stars since the movie had just came out. It was checked out but I found instead An Abundance of Katherine’s and decided to read it just because. Being recently dumped by the same guy for the fourth time I was shocked at how much I connected to the novel. I especially enjoyed the part where Colin acknowledged that getting K-19 back could never fill the hole created within him from missing her. I was just looking for a book to read for fun not knowing it would entirely change my perspective on my previous relationship (or relationships depending on if you count dating the same person more than once as more than one relationship). I finally understand how I feel towards him as I identify with Colin. Thank you for writing a book that captures how I (and I’m assuming many other 17 year old dumpees) feel. Plus I’m totally in love with anything having to do with algebra based math.
With sincere gratitude,
Karyn.

Hi John,
I highly doubt you are going to see this, because duh you have a lot of other important things to do. But I really wanted to say thank you, and i didn’t know any other way to do it except writing here and I HAD TO DO IT BECAUSE I’M FILED WITH EXCITEMENT AND THANKFULNESS AND I MIGHT EXPLODE IF I DON’T SAY ANYTHING. So, thank you for inspiring me. Also a sarcastic “thank you” for the 4th book by you that I just finished. Can’t help but feeling empty. Why do books have to end?
John, keep being awesome and keep being such a great inspiration. Btw, I absolutely love your videos. You and Hank never fail to make my day.
I should probably tell you that one of my goals in life is meeting you, because you are a wonderful human being.
Thank you ( a real big genuine thank you).

Your future friend

Okay so I’m sorry if this gets annoying because I’m going to post this in a lot of places so that it’s more likely you see it but: I’m Autumn. I’m 14 years old. I live in Houston, Texas. I would like to be you for Halloween. I don’t care if I’m a girl. I would vlog while dressed up like you, but I don’t know what I would wear. I have some ideas but I am curious to how YOU want me to portray you. Is there anything specific you would want me to wear or have on my person? I think you are an awesome person and am so very excited to get to be you for a night. Thank you for being you and please let me know how you think I should dress up. ~Autumn

Not in the first person, unlike all your other books. I like that.

‘Hi…’
so it had been my birthday recently, i have discovered a fascination with literature lately, so i had decide to have a strictly only money and books policy.
i had already read The Fault In Our Stars, and i very much enjoyed it, so next i moved on to Paper Towns which i loved deeply (on of my favorite books) then i continued my streak with The Abundance Of Katherines, and i could now put it down. (Finished it at 2am) i coudn’t help but picture Troye Sivan as Colin.
to put it lightly i have not let go of Looking For Alaska, i would see a movie version of any of your books and i sit here waiting for another John Green Spectacular.
‘…Hi’
