An Abundance of Katherines by Jhon GreenBook Summary

This is a story about a boy named Colin Singleton, whose biggest ambition in life is to get recognition of the world as a ‘genius’ by providing a scientific marvel. Colin is shown to have a peculiar love life. Throughout his life, he has dated and got dumped by 19 girls who all bear the same name, Katherine. When he gets dumped by Katherine XIX, Hassan, who is Colin’s best friend, urges his friend to embark upon a road trip in order to get his mind off the break up.

They travel all the way up to Tennessee, where they meet a girl named Lindsey Lee Wells. She is the daughter of a local factory owner, Hollis. Colin and Hassan decided to work with Hollis and are provided with food and accommodation at her house. They are assigned to go door to door, to every house in Gutshot, Tennessee and compile an oral history of the town.

As the time passes, Colin starts to develop feelings for Lindsey, who is stuck in an unhappy relationship with her boyfriend, also named Colin. He is referred to as ‘the other Colin’ or simply as TOC by Hassan and Colin in order to keep track of which Colin is the conversation about. Getting spurred on by his ambition for a ‘eureka’ moment, Colin finally develops a theorem which he names as the ‘Theorem of Underlying Katherine Probability.’ He takes a look back at his life and finds out that his theory is applicable to all his past relationships. The theorem takes into account many factors and dynamics of a relationship before predicting its chances of success or failure.

In the meanwhile, Hassan gets a new girlfriend named, Katrina. However, their relationship fail to last long because Katrina and TOC are found making out with one another. Lindsey is disgusted and disappears into her secret hideout. She is later discovered by Colin, who tells her all about his past relationships and she also vents out her frustrations. They both then declare their love for each other. Colin also discovers that his theorem can only explain why a relationship failed and not predict its future.

The book ends with Hassan, Colin and Lindsey going on a drive again. They decide not to stop and let the road, take them wherever it may.


The book was well liked by the critics and the fans. It was the runners up for the 2007 Michael L. Printz Award and also got recognition as being one of the best books for teenagers by the American Library Association. The Guardian Review gave the book 6/10 rating, praising the plot and the depth of the characters introduced by Mr. Green.

The Book Smugglers Review praised Mr. Green for his writing and claimed that An Abundance of Katherines is one of his finest works.

The book was released on September 21, 2006. It also includes an appendix written by Green’s friend, Daniel Bliss. The appendix contains details of the several complicated equations employed by Colin in order to derive his Theorem.
