We are all made of Molecules by Susin Nielson

This is what I consider a nice, cozy YA book, it has all the elements of a story that teaches the saying "Don't judge a book by its cover". Stewart is the nerdy boy in school and Ashley is the Queen Bee, both teens have nothing to do with the other until...their parents decide to move in together. The novel follows the two teens navigating their parents relationship, new living arrangements and prejudgements about each other.
