Memory was supposed
to save us.

Sarah Bailey has spent her life haunted by a childhood catastrophe she cannot fully remember. Now a doctor in the quiet Missouri town of Midwater, she begins treating patients with violent neurological symptoms, blackened eyes, and memories that seem to belong to someone else.

Deep beneath the Nevada desert, neuroscientist Abigail Reid helps lead Project Mnemosyne, a classified experiment designed to map and preserve the human mind. When Abigail discovers secret work built around her research, the project’s promise becomes something far more dangerous: a system capable of reaching beyond the laboratory and into countless unsuspecting lives.

As Midwater’s residents begin sharing impossible visions and familiar people turn unpredictable, Sarah and Abigail are drawn toward the same hidden source. One must survive a town losing its grip on reality. The other must expose the machine that may be rewriting it.
