A past. A debt. A reckoning. A murder.

After her aunt's death, Winter Covington and her mother inherit her beach house in a quiet seaside town. Unfortunately for them, they arrive just as dead bodies begin washing up on shore. Both residents and tourists are terrorized by the suspected rogue shark and wonder if it's safe to go into the ocean.

But Winter wonders if there's something, or someone, more dangerous lurking on land.

As she tries to solve the mystery surrounding her aunt's death, Winter finds herself trying to avoid becoming the next victim, especially when all signs point to her roommate being a killer.
