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.
If you are fully prepared to be inundated with spoilers, you can learn much, much more about Katherines at the book’s Questions page.

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,

Cassandra

Hello dear Mr. Green,

I’ve been reading your books and I have to say: YOUR BOOKS WAS THE BEST BOOKS THAT I’VE EVER READ!
I read this book in 3 days, in 8 hours. I dreamed with this book and I just wanna say thank you so much for all your books. And I think I wrote many “book” in this comment, but okay. Okay? Okay.
I want to ask you to make a movie of this book, after Paper Towns. Think of it.
Finally, i wanna say thank you again and that I love your books and I love you too.
Kisses for you and your family.

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

Dear Mr. Green
I think your books are brilliant. There’s a lot to learn in each of your books. But I believe this is my favorite. I don’t know if you intended this to be part of the moral for “An Abundance of Katherines” but I like the diversity of beliefs the characters have and the fact that the bond between them does not change because of that. Also it is preocupating how the words Islam, Arabs or Muslims are by most people directly linked with the word terrorist, and I think Hassan is a brilliant way to change that and maybe even other ideas we make about people in our head. I’m Jewish and where I live people believe that every Jewish person is wealthy, which is not really the case, there are some people that rely on donations and are in fact not even stable. The wealthy are such a small minority that it is kind of ridiculous. I learned lots of other things from this book as well as from your other books but I wanted you to know that even though this is not your most famous or bestselling book or whatever, it is amazing. And I adored it.

Sincerely yours, taniazakay.

P.s Don’t forget to be awesome.

I have read only two chapters of the book “An abundance of Katharines” I guess I can’t tell my opinion after reading this only two chapter. But the people and the reviews on the Internet didn’t encourage me at all. But I just have to continue reading to find out by myself. And thank you for writing”the fault in our stars” you can say that this book make my whole year …. I know it was such a tragic story, but It’s still my favorite book.
I’m Egyptian by the way …. Just to make you sure, you have fans all over the world.

Dear Sir,
I am a high school literature and history teacher and have enjoyed your work in the past. Today, I came across a copy of Katherines, that one of my students is reading, and found the creation and layout of the text to be interesting. Previously, I attempted to develop a Creative Non-Fiction piece that used similarly place text and interjections of post-thought writing.
I have yet to read the work completely but quickly thumbed through a chapter and photographed some of the pages. I am curious about your writing process and wonder as to how you developed the footnotes. Was it completely a post writing objective or was it completed simultaneously as you generated the original text and turned into footnotes at a later date?

Thanking you greatly for you work and incite,

Basketball doesn’t have to be purely rule controlled play with an indoor wood court. There are many various variations about the game which bring basketball to some whole brand new level. Variety is among the things which makes basketball this type of popular activity. http://www.scorespro.com

Dear Mr. John Green,
I loved this book so very much and of all your books so far I have read The Fault in Our Stars (of course) let it snow (which I know is a joint book but it was amazing) and an abundance of Katherine’s. I am currently reading paper towns and I’ve got to say I love it. I really hope you read this and it puts a smile on your face and I know there are over 500 comments but I really want you too read this. Thank you if you do read this and you are by far the best author I know!
Yours Sincerly

Monsieur Green,
Je suis vraiment désolée de vous écrire en français, mais je ne parle pas assez bien l’anglais pour le faire dans votre si belle langue. Alors j’espère que vous n’êtes pas comme moi et que vous connaissez un petit peu le français.
Je viens de terminer votre livre, à la seconde même ou j’écris, et j’ai adoré. Tout simplement. J’ai déjà lu “Looking for Alaska” et “The fault in our star” et j’ai aussi beaucoup aimé. Mais ce que je préfère, vraiment, ce sont les petites manies de vos personnages. Apprendre les dernières paroles de personnes célèbres ou faire des anagrammes. Je m’y retrouve beaucoup, car moi je cherche un rime à chaque prénom ou nom de famille que j’entends.
Je vous admire beaucoup, car j’essaie moi aussi d’écrire, mais vous arrivez à mettre ce petit truc, dans vos personnages, que je ne trouve pas. En fait, ils ne sont pas parfaits. Ils ont comme nous, avec leurs défauts et leurs qualités et c’est ce qui les rend si attachants.
Encore merci pour ces immenses moments de plaisir passés à vous lire.

PS: Je pense que ce serai génial de créer un site internet pour avoir la courbe d’une relation, et que chacun puisse faire la sienne. Il suffirai de rentrer les variables pour l’avoir. Mais c’est juste une idée en l’air, comme ça :)

Dear , Mr. Green
I liked your book it was very interesting how the Colin character turned to be, and I also loved the ending because “not every book is a happily ever after”. It shows us teenagers how real life is you get dumped and you also dump people.

At the same time, the visitors are intelligent too; studying even the first passage of the information they also understand that the written statement does not have the creativity and is not up to the mark. raspberry ketones amazon

Olá, Mr. Green, estou fazendo um trabalho escolar sobre seu livro, O teorema Katherine. Gostaria de saber algumas coisas em relação a história do livro, informações do tipo quando foi escrito? quando foi traduzido pro português e lançado no Brasil? o que te inspirou a fazer esse livro? algum de seus outros livros te ajudou a criar esse? porque ele não é tão “depressivo” como os outros?
Se puder me responder essas perguntas ficarei muito grata.

Atentamente Bianca Dias
Beijos.

Hello, Mr. Green, I’m doing a school project on his book, An Abundance of Katherines. I would like to know a few things about the history of the book, type information when it was written? when it was translated and released pro Portuguese in Brazil? What inspired you to do this book? some of his other books helped you this? because it is not as “depressed” like the others?
If you can answer me these questions I will be very grateful.

Hello, Mr. Green
I’m not sure that you’ll read that, but it’s okay. I’m from another country. It’s called Moldova and I’m sorry if my english is bad. I really want to say thank you ’cause your books have made me better! I had begun to think more and I
understood, life is beautiful! I was really happy to read your books and then to see my favorite actors ( Shailene Woodley, Nat Wolf, Ansel Elgort, Cara Delevigne) in movies. I know that milions of people love your books, abd I’m glad to be one of them! Thanks for you and your family! Good luck!

John Green:
I´ve been reading your books, the only two I´m missing are WG WG and Let it Snow. I love the way you write, even I´m from mexico and I read An Abundance of Katherines in English it easy for me to understand all the expressions we don´t use here. I think my favourite book that you´ve written is An Abundance of Katherines. Although it is not the book that contains the most “John Green” I think the one anybody can say: “that´s written by John Green” is Paper Towns. That one is like 1000% John Green. I just love everything you write. My favourite character I think is Colin, he´s really adorable. I really enjoyed that character.
Now, I would like to know 1) if you will read this comment 2) which is your favourite character from all the books you´ve already written and, of course 3) if you don´t matter that list I´ve already done on the last words.
IF YOU READ THE COMMENTS -PLEASE- REPLY.
I just love your books and I´m here sited behind my father that´s telling me to go to bed, so I have to go.
Continue doing that incredible thing you do with your thoughts and fingers, it´s perfect.
Love,
Karla.
