内容简介：
Anonymous letters, murder theories, and a local ghost legend confront Jody Barrett when he arrives for his summer job at Lake Marilee, where locals mistake him for a teenager who died in a diving accident last fall. For Jody, who trusts nobody but himself and his atheistic history teacher back home, things rapidly get complicated as he finds himself on a battleground of fact vs. fiction, right vs. wrong, and good vs. evil. Although bright and self-confident, he meets his intellectual match in Kristel Schuple, the attractive daughter of the resort owner. Her boldness, charm, and Christian apologetics force Jody to confront truths he wishes never existed: truths about his family, his values, and his creator. As Jody and Kristel seek to unveil the Ambassador for the Dead and the mysterious Marilee legend, their lives are propelled into jeopardy in a struggle to preserve our most valuable resource, truth itself.
