Between Worlds — Amanda Zabski

Jaime Nevin struggles with her identity as much as any sixteen-year-old girl. Well, maybe a little more. Jaime just discovered that she is not human -- at least not exactly. The child of a doomed union between a noble of the Unseelie Court and a Seelie Fae, Jaime has been raised by her mother hidden away from both courts in a small New England town.

Troubled by vivid dreams when asleep and plagued by paralyzing headaches when awake, Jaime knows something is wrong. After the strange disappearance of her mother, and the unexpected appearance of family she never knew, Jaime is forced to accept a truth about her past that puts her future at risk.

To make matters worse, while she works to determine who to trust, Jaime's best friend Allie keeps a powerful secret from her.

Thrown into a world she doesn't understand, Jaime must use her fledgling powers in a fight to stay alive and avoid capture by the Keeper, a soulless creature that frightens even the things that go bump in the night.
