Racing the Dark (Spirit Binders)

Like the other women of her island, Lana expected to become a diver, harvesting jewels from a native fish. But during her initiation dive, she finds a blood-red jewel that marks her as someone with power. Though she hides the jewel, the mark it represents will drive her away from her home island and into an apprenticeship with a one-armed witch. Alaya Dawn Johnson has created an unforgettable coming-of-age story set in a world where wielding the power of magic requires understanding the true meaning of sacrifice.
