Driving home from a bonfire party, eighteen-year-old John Hawk crashes, killing his girlfriend, Riley. Bullied and tormented at school, and crushed by his guilty conscience, John transfers to a school on the banks of the Mississippi River, where he attracts the eye of the principal's daughter, Megan. Though he's reluctant, she convinces him to be her prom date. The morning after prom, Principal Jones reports Megan missing. Four days later, her body is recovered from the river, and John becomes the prime suspect in her death. Charley Cotton, Megan's best friend, knows that Megan had a secret, but she doesn't trust John because of his past. John is desperate to avoid adding to the shame he carries for Riley's death, though-it's destroying his life. With Charley's help, he learns that others in Megan's life had a motive to keep her quiet. But every effort they make to uncover the truth edges them closer to a desperate murderer with everything to lose.
