Back home on the shores of Lake Erie for the first time in years, Natalie St. John plans to visit old friends, mend a broken heart, and take a break from her busy veterinarian practice. But her peace is shattered her first night back, when she discovers the murdered body of her friend, Tamara Peyton.

But neither Natalie nor Sheriff Nick Meredith recognizes the face of the devious killer who walks among them, hiding behind a well-crafted lie. Now, a murderer's deadly act of vengeance demands one more sacrifice - and Natalie has been chosen to pay the price.
