From New York Times best-selling author Jeffery Deaver comes a tale of a bucolic getaway and an unsettling spirit.Amanda and Charlie are spending their first weekend away in months. They've rented a luxurious vacation house on Lost Valley Lake. Swimming, bicycling, and romance are the order of the day, and all is good. That is, until someone - or something - appears on the shore across the lake, just as the sky turns gray and the water chill and choppy. When the apparition, or whatever it might be, grows closer and closer, it soon becomes clear that there are certain types of evil that you can't protect yourself from with locked doors and windows. And perhaps you can't protect yourself from them at all.
