Deputy Carly Jenson messed up big time, and now here she is, stuck on a fishing boat at nightfall, bored out of her mind as divers troll the bottom of a dying lake for evidence of a petty small-town crime. Carly's not winning any commendations. Until the divers report in, that is. They found something at the bottom of the lake. Something that sholdn't be there. Something they can't explain. Something that will turn Carly Jenson's boring night into a horrifying ordeal of chaos and sheer terror.
