Circle of Grace — Jan King

In the past, three gifted sisters live through a night of terror and heartbreak, when each of them make a decision that ends in tragedy...and a curse that causes a massive ship to burn for centuries on the midnight water of the Atlantic. In the present, Catherine Gallagher is content with her life on a mystical Maritime island, when she is thrown into a nightmare world of reincarnation by a not-so-mortal being, who calmly informs her she's lived before, and that she is expected to risk her life to avenge 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 love interest, and a very human stalker, possessed by the past, who is bent on destroying her...
