Tony Wagner feels aimless. He loves his hectic family life, with 3 kids and 3 foster daughters. But he has lost interest in his job as a national park ranger. And, even though an FBI psychiatrist has cleared him to work, no agents have asked him to consult on a case. Then, Agent Wyatt Garret calls. He has been summoned to Maine to investigate the death of a former ambassador's son. Greg O'Connor has fallen from the South Face of the Precipice in Acadia National Park. Was it murder, suicide, or just a climbing accident? Garret needs Tony to search for evidence on the cliff face. He also admits that other agents are cautious about using Tony. They worry that the trauma of a year earlier will effect how he reacts under pressure. Before the case is solved, they will find out.
