When lives are threatened, are some secrets better left hidden?

Bailey Craig vowed never to set foot in Yancey, Alaska, again. She has a past, and a reputation --- and Yancey's a town that doesn't forget. She's returned only to bury a loved one killed in the plane crash, but then dark evidence emerges and Bailey's own expertise becomes invaluable for the case.

Cole McKenna can face dangerous rescue dives. He can face the fear a murderer may be threatening his town. But facing the reality of Bailey's reappearance is a tougher challenge. She broke his heart... but doesn't seem to be the same girl who left Yancey 10 years ago. And he's not the same guy she left behind.

Racing against the clock and a rising body count, Bailey and Cole must move beyond the hurts of their pasts to work together until the truth of what is hidden in the depths finally surfaces.
