When a young gymnast dies performing a world-famous stunt, Kiernan suspects foul play.

As a young girl in Baltimore, Kiernan O’Shaughnessy lived for gymnastics, where strict discipline and endless practice kept her centered even as her life fell apart. Her idol was stuntman Greg Gaige. Famous for pulling off the moves no one else could, and for scorning safety equipment, Gaige was the one man O’Shaughnessy truly admired.

Ten years after Gaige’s tragic death, O’Shaughnessy is a private detective on the California coast, and a young female gymnast has come along to challenge Gaige’s crown. O’Shaughnessy goes to watch the girl attempt the death-defying Gaige Move, without a harness, on the edge of a seaside cliff. After a perfect landing, the ground gives way and the gymnast falls to her death. The police call it an accident, but O’Shaughnessy is determined to get the truth—in honor of her old hero, and for the young woman who looked up to him the way she did.
