★ "A razor-sharp sequel" —Kirkus Reviews, starred reviewNew York Times bestselling author Ellie Marney returns with an electrifying, chilling thriller that follows junior FBI consultants Travis Bell and Emma Lewis with a new case that may unravel everything they’ve been working for. After a harrowing encounter with juvenile sociopath Simon Gutmunsson, junior FBI consultants Emma Lewis and Travis Bell went their separate ways: Emma rejected her Quantico offer, and Travis stayed to train within a new unit of the Behavioral Science division. But the unit’s latest case is feeling eerily familiar, and Kristin Gutmunsson—Simon's eccentric twin—reaches out to Travis to send a warning: Emma is in peril.   When new evidence points to a copycat of Daniel Huxton, the serial killer that she escaped, Emma returns to Quantico and is thrown back into her past traumas. Compelled to prevent more tragedy—even if it means putting herself in danger—she looks to Simon once again. But can he be trusted to help stop the killer before time runs out for his next victims?
