Gil Montgomery, a cadet in the Temporal Counseling Program, can't wait to pass her field exam and become a professional time surfer. The TEMCO program targets death-row offenders for time-based counseling while they're children. For her exam, Gil will travel 24 years into the past to counsel 10-year-old Danny Winston before he murders his abusive babysitter, Rick Olsen. Preventing the stabbing should stop the chain of events leading to Danny's eventual execution. Gil's assignment seems simple until her advisor, Dr. William Ableman, learns that Rick is a serial killer targeting Danny's mother. If Gil stays and protects the Winstons, she might not survive. William wants the woman he loves to be pulled from the field, but if Gil fails to complete her assignment, it will unleash a Time Tsunami and destroy the timeline. As TEMCO undergoes an emergency lockdown and Gil's fellow cadets try to figure out what's happening, Gil and William learn the importance of faith and the price of true love. Everyone's fate is resting in Gil's hands, but does she have the strength she needs to defeat a ruthless serial killer intent on annihilating everyone in his path?
