This Raging Sea

Summary:

Historic Loch Creek is a witch-like tourist trap in New England, but for Briar, it's just a trap, because she's convinced she'll die there. In the waves that swallowed her twin brother thirteen years ago. But when her best friend Finn, whom she's loved since childhood, disappears from the seaside carnival, there's only one person who can help Briar find him: Morgan, her greatest enemy, who knows her darkest secret.  

As Briar uncovers hidden truths as deep and dark as the water that pursues her, it quickly becomes clear that Finn has gone farther than anyone could have imagined. He is lost in time, and neither of them is safe. Should Briar and Finn look too closely, they might find terrifying answers, not only about what lies buried beneath the shore, but also about the threads that bind them together.

As past and future collide, the seductive but evil underwater creature that Briar wants to claim for itself still needs its victim…
