Every John Green Book Ranked, Because Your Summer Needs All the YA Love

The quirk factor is strong with this one. An Abundance of Katherines tells the story a former child prodigy's quest to create a formula for love after being dumped by 19 different girls named Katherine. Add in a road trip with his slacker best friend, and you have a fun coming-of-age novel about stepping outside your comfort zone. It's zippy, a bit odd, but ultimately full of heart and a youthful energy that will keep you turning the pages until you reach the story's somewhat inevitable (but nonetheless charming) conclusion.
