Thief Eyes — Janni Lee Simner

After her mother mysteriously disappears, sixteen-year-old Haley convinces her father to take her to Iceland, where her mother was last seen. There, amidst the ancient fissures and crevices of that volcanic island, Haley meets gorgeous Ari, a boy with a dangerous side who appoints himself her protector.

When Haley picks up a silver coin that entangles her in a spell cast by her ancestor Hallgerd, she discovers that Hallgerd's spell and her mother's disappearance are connected to a chain of events that could unleash terrifying powers and consume the world. Haley must find a way to contain the growing fires of the spell--and her growing attraction to Ari.
