Becca Simpson is a not so average teenager, and she knows it. In fact, she embraces it. She was cho-sen to be a Keeper, one who keeps the gates sealed between the magic world and the "normal" world. The only time she isn't safe from the dark creatures of the Other Side is the Dark Hour. Every night, at the same time, the gates between the two worlds open and Becca is left vulnerable until the gate closes and the minions disappear. But that's why she has Erik Manchester. As her Guardian, Erik is in charge of making sure no one, or no thing, comes after her to take her away. Because waiting for her on the Other Side is a tyrannical emperor, looking to use her status to meld the two worlds into one. With Erik, Becca feels safe, but suffocated. There are rules she has to follow in order to keep out of the hands of the emperor. Then Kyne walks into her life and challenges everything she knows. Not only does he know things about the Other Side, but he's from there. And found a way to stay in the normal world without frying.
