An Abundance of Katherines by John Green, 227 pages
Colin Singleton is a self-defined washed-up child prodigy. He recently graduated from high school and was dumped by his girlfriend Katherine (marking the 19th time he's been dumped by someone with that name), and as such is feeling a bit lost. In attempt to clear his head, Colin and his Judge Judy-loving best friend Hassan head off on a road trip that takes them to Gutshot, Tennessee, where they get to know the locals while Colin works on a mathematical theorem that would explain romantic relationships.
Like all of Green's books, this one is quirky and brilliantly brings to life the awkwardness of the teenage years. While An Abundance of Katherines doesn't have the buzz of The Fault in Our Stars or Paper Towns (both of which were made into movies) or Green's debut, Looking for Alaska (a Printz Award-winner that's also carved out a near-permanent on ALA's frequently challenged books list), Colin's fascination with anagrams and trivia, as well as the absurdity of attempting to mathematically explain love, make this my favorite of Green's books. It's sweet, it's funny, and it's awesome.
