What is the real story beneath shadow lake?

In an instant Anna Collins loses control of her car and careens into isolated Shadow Lake. Near death, she's rescued by a man named Jack Fairbanks. But how could that be? Everyone says that the reclusive Fairbanks, scion of a powerful political family, is dead. Anna is sure Jack's astonishing appearance is related to the hit-and-run that killed her son and destroyed her marriage. But when her friend's body is discovered in Anna's waterlogged trunk, she's not sure what to believe anymore. How did the body get there? Is Anna actually a murderer? Only one person knows, but finding him threatens to expose Anna to a deadly encounter on the banks of Shadow Lake.
