In 2018, NYPD robbery division detective Barry Sutton answers a “jumper” call. The woman has indeed been robbed—of her son, her husband, her entire life. She is suffering from FMS—False Memory Syndrome—a mysterious disease that makes those afflicted remember two different lifetimes simultaneously. Meanwhile, in 2008, the brilliant neuroscientist Helena Smith receives unlimited funding from a recluse billionaire to study memory to cure Alzheimer’s. Thus begins Crouch’s mind-blowing, convoluted, and surprisingly romantic science fiction thriller, which grapples with profound themes of memory, identity, and time, asking us what are we willing to sacrifice to rewrite the past—and what will remain of us if we do.
