On the verge of turning sixteen years old and getting her driver's license, Samantha Wright deals with life and school like most every other teenage girl in Klamath Falls, Oregon. Sure, she has some issues with her dad and her stepmom, and she misses her mother, who has died. But Sam is not prepared for the changes this school year brings. As the year gets underway, Sam and her best friend, Sarah, meet new students-like the hot guy with the purple hair-and they tackle their new classes. But soon Sam starts acting strangely, mumbling incoherent thoughts and losing moments of time. She hears strange noises and screaming from the nearby forest. Inadvertently, she discovers Two Moons, a strange new world with mystical creatures-some who want her and some who want her dead. She is shocked to find that she is the "chosen one"-the only one who can stop the clash between the Blood Vampires and the Free Vampires. With old friends and new, she is determined to see this conflict to the end and to get the answers about these two very different worlds.
