Alex Bryant is pissed at her mother, but what else is new? She’s spent most of her life picking up after her charismatic but scatterbrained mom, Cassie, who is always on some new get-cash-quick scheme. This latest one—a scientific study in memory implantation, with Alex as a fellow test subject—is sure to be a total flop. That is, unless the memory study answers Alex’s questions: who is her father, and where is he now?  

When the experiment actually works and flashes of Cassie’s memories while pregnant with Alex appear in her mind, Alex thinks it just might have been worth it. But soon, calamity strikes when the memories reveal a decades-old murder that present-Cassie swears never happened. Discovering the truth someone tried to keep buried in the past sends Alex and Cassie on the run from a threat they never saw coming: their own minds.   

New York Times bestselling author of the Pretty Little Liars series Sara Shepard teams up with author Ellen Goodlett (author of the Rule duology) for this sci-fi thriller perfect for fans of Inception and Blake Crouch’s Recursion.
