Unemployed and in need of cash, recent college graduate Alex Bryant reluctantly agrees to participate in a scientific study on memory implantation with her eclectic (and somewhat irresponsible) mother, Cassie.
To test whether the experiment worked, Alex and Cassie re-trace the road trip from the memory in question. But Alex is distracted: both by the secret she’s keeping and questions her mother refuses to answer.
Alex struggles to bond with her mother while simultaneously experiencing flashes of Cassie’s past—a past that Cassie doesn’t seem to remember, involving a man she refuses to talk about.
While riding the roller coasters at the next stop on memory lane, Alex gets a clue about where her mother was headed on this road trip twenty-one years ago.
The secret Alex is keeping starts catching up to her, and so are her mother’s memories—including a vivid one of a woman drowning Cassie while she was pregnant. Then, without warning: someone betrays Alex’s trust.
Cassie takes Alex somewhere she knows they’ll be safe from Dr. Novik: Amizade, a self-sustainable wellness community, and a place Cassie once called home. But instead of getting answers, Alex only has more questions.
Surrounded by her mother’s past and worried for her future, Alex learns the consequences of her actions. If someone didn’t try to murder Cassie while pregnant, what did happen?
The true damage done to Cassie’s memories is revealed—as is the identity of Alex’s father.
