...Circle of Grace by Jan King, the first in the Island Magic Trilogy

In the past, three gifted sisters live through a night of terror and heartbreak, when each of them makes a decision that can only end in tragedy...and in a curse that will cause a massive ship to burn for centuries on the midnight waters of the Altantic.

In the present, Catherine Gallagher is content with her life on a beautiful, mystical island, until she is thrown into a nightmare world of reincarnation by a not-so-mortal being, who calmly tells her she's lived before, and is expected to risk her life to lay to rest the spirit of the doomed girl she once was!

Added to the mix are two friends who must be dragged, kicking and screaming, into the fray, a sexy new love interest, and a very human stalker, possessed by an evil entity from the past, who is bent on destroying her...
