49. Blue Lily, Lily Blue by Maggie Stiefvater
Dead Welsh kings, raven boys, school crests, Latin classes, a house full of psychics, a 1973 Camaro, street racing, caves, a magical forest that moves, missing mothers, friendly hit men, and a girl who makes "energy" stronger-- this is Maggie Stiefvater's series. Blue Lily, Lily Blue is the third book, preceded by The Raven Boys and The Dream Thieves, both of which are stunning. Delve into the world of fast cars and sleeping kings for a few hours--it will most definitely be worth it.
