Oscar-nominated screenwriter Heisserer debuts with a mind-bending sci-fi thriller. Grant Lukather works for Homeland Security’s Predictive Analytics unit, which investigates people who’ve tipped off the authorities to mass-casualty events. After an anonymous 911 caller accurately warns dispatchers that seven people will be killed by a pipeline explosion near Albuquerque, N.Mex., Grant traces the call to past-lives therapist Sarah Newcomb, and learns that she got the information from a patient, Marigold Chu. After Marigold proves she was uninvolved in the blast, she reveals to Grant that, through her work with Sarah, she’s capable of accessing other people’s lives and memories—including those from the future.. One of the people Marigold has a psychic link with is Denver police detective Brian Huntley, who’s in charge of the search for a prolific murderer known as the Ash Killer. Grant enlists both women’s help, hoping to use Marigold’s gift to ensure Huntley catches the killer. As his plan unfolds, the fabric of reality twists in unexpected ways. Heisserer’s nuanced characterizations make it easy to buy into his plot, which dazzles with its manipulations of time and its jaw-dropping reveals. This auspicious first outing will excite fans of Blake Crouch. Agent: Mollie Glick, CAA. (Oct.)
