Loch Ness holds secrets, ancient and deadly. Does a monster inhabit its depths, or is it just myth? Marine biologist Zachary Wallace knows, but the shock of his near-drowning as a child on the Loch has buried all memories of the incident. Now, a near-death experience suffered while on expedition in the Sargasso Sea has caused these long-forgotten memories to resurface. Unable to cope, his career all but over, he stumbles down a path of self-destruction until contact from his estranged father. Now Zach's father is on trial for murdering his business partner, and only Zach can prove his innocence--if he is innocent. But doing so means confronting the nightmare that nearly killed him seventeen years ago.
