Loch Ness holds secrets, ancient and deadly. Does a monster inhabit its depths, or is it just myth? Why, after thousands of reported sightings and dozens of expeditions, is there still no hard evidence?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. Haunted by vivid night terrors, stricken by a sudden fear of the water, Zach finds he can no longer function as a scientist. Unable to cope, his career all but over, he stumbles down a path of self-destruction until contact from his estranged father, a man he hasn't seen since his parents divorced and he left Scotland as a boy. 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 . . .
