Will Grayson, Will Grayson by David Levithan and John Green

These two are geniuses, and I mean Levithan and Green, however the teenaged Will Grayson's are unforgettable too.  Alternating chapters between the Will Grayson's provides an insight into each as individuals until their serendipitous meeting in an adult video store.  Tiny, whose real name is not Will Grayson, has a starring role as the best friend of one WG and as the boyfriend of OWG (Other Will Grayson).  Both WG's lives become intertwined after their meeting and eventually learn a lot about themselves in this hilarious coming-of-age story.  I highly recommend listening to this book, the actors are phenomenal as well and brought the characters to life.
