Danger lurks on the horizon, leaving only two choices: find shelter or flee.

Cassidy Livingston's new identity has begun to feel as comfortable as her favorite sweater. She's been tucked away on Lantern Beach for weeks, waiting to testify against a deadly gang, and is settling in to a new life she wants to last forever.

When she thinks she spots someone malevolent from her past, panic swells inside her. If an enemy has found her, Cassidy won't be the only one who's a target. Everyone she's come to love will also be at risk.

Dangerous waters threaten to pull her into an overpowering chasm she may never escape. Can Cassidy survive what lies ahead? Or has the tide fatally turned against her?
