Nick & Norah's Infinite Playlist.

Never was much of a reader, however this is one of my all-time favorite books.
Haven't bought another since, because I'm stuck reading this one time and time again.
I love how it's written, I love how everyone can relate to BOTH characters, and I love the vulgarity of the entire story.
For mature readers only.
Go get a copy =]
