The Bourne Identity meets I Am the Cheese in this taut thriller

Even though Micah's a star pitcher, his older sister Lindsey is the real deal--a runner so good, she has a shot at the Olympics. The two of them urge each other on, and are each other's best support. Then the unthinkable happens: Lindsey is murdered, and Micah may have been the last person to see her. But he can't remember what happened, no matter what their parents tell him, no matter what the police say. Did he witness his sister's murder--or commit it? Can he recall the truth before his life is sentenced to end, too?
