While An Abundance of Katherines may be John Green’s least best selling book, it still remains quite intelligent, unique, and important. While I could spend more time on introducing it now, I feel that anything I say at this point before my list will only include one of the 19 things in my list. So without any further ado….

1. The Title—unashamedly tells you “this is a nerdy book about a girl” and that’s ok.
2. The cover design—It was actually designed by fans in a contest. 
3. It has an appendix (by Daniel Bliss)—How many young adult contemporary romantic/literary/ buddy comedy/novels have an appendix to explain things further?
4. The main character’s name is a pun— Colin Singleton. First of all, he feels his problem relates to his being single, or rather, found single. Secondly, a “singleton” is someone born without a twin. He feels he is missing a twin, another piece, to complete himself. He must solve the formula.
5. It is the only John Green novel written in 3rd person—Green explained that it’s because Colin himself doesn’t know hot to tell a good story. That’s part of his problem.
6. The book has footnotes—Like the appendix, the footnotes give us information supplemental to the narrative. This enhances the story, but is not essential. It also helps see a different way to take in a story. After all, how many of us pause a reading to look something up anyway?
7. There are 19 Katherines, and 19 chapters—The chapter numbers were planned to reflect the number of girls who dumbed Colin.
8. The narrative is non-linear—The story is told in flashbacks, specifically flashbacks to previous Katherines. Colin’s current journey causes him to reflect on his past relationships. Subconsciously, he is good at telling stories, he just hasn’t become aware of it yet.
9. An abundance of anagrams—Not only is it a perk for those who love anagrams. Green also says that they “say something about the malleability of language” which can be “twisted and molded.” Language, like the stories it tells, can be altered, reshaped.
10. Colin is a character for prodigies who aren’t geniuses—It’s an ideal book for smart teens who feel they’re just not smart enough to be recognized. But I won’t say why. I’m not spoiler.
11. Hassan challenges our definition of faith—Hassan has defined his faith, and his life, by living according to what not to do. But what about the things we are to do?
12. There’s plenty of math—You don’t have to get it to enjoy the story, but Colin works up a math theorem he feels he must solve. It’s a legit math theorem that can be worked through, for math geeks.
13. The book makes tampon strings seem beautiful—Don’t even ask.
14. It has the following quote—”There’s no level of fame or genius that allows you to transcend oblivion.”
15. This—The amount of random facts in it are bound to make you smarter, even if you don’t get anything else out of the story.
16. It has “Romance, adventure, morals, everything”—Yep.
17. It’s a lesson about history, and a lesson about what matters—You just have to read it to see why.
18. It almost won the Michael L. Printz Award— It was placed as an Honor book.
19. It is the only John Green novel not yet adapted into a film—yet

But you can decide for yourself whether you’ll read it.
