An Abundance of Katherines / John Green / 228 pages

Colin Singleton is a prodigy wondering if he's lost it.   Colin Singleton is a socially awkward teen who has dated and been dumped by 18 girls named Katharine.  Colin Singleton is a nerd who decides to create an algorithm for predicting the length of a relationship and who will be the dumper and who will be the dumpee. I can see what teens gleefully flock to books by John Green.  He's in their heads.  This is a funny and thoughtful book in which Colin grows as a character.  Definitely has great appeal for high school students!  Green can even make math look interesting.
