Invisibility by Andrea Cremer and David Levithan
I pre-ordered this book in January (because I have adored books by both of these authors). I am loving this book so far. Having one of the main characters be invisible is pretty darn intriguing. I can't wait to find out why he's invisible and how exactly a relationship will work. Having two distinct points of view and having each character written by one author is really fun/interesting to read.
