A mind-bending speculative thriller where past lives collide with present danger and the
truth follows you across every timeline.
Federal agent Grant Lukather works in a shadow division of Homeland Security known only as Predictive Analytics, a unit trained to detect catastrophic events before they occur. When an anonymous tip warns of a deadly explosion in New Mexico, the case quickly spirals into something no model or agent has ever prepared for. Grant’s search leads him to Sarah Newcomb, a therapist whose unusual method of past-life
hypnosis has revealed something impossible: a pattern connecting her patients to crimes happening right now.
As Grant investigates a disturbing copycat murder in Colorado, the two uncover a phenomenon that stretches across multiple states, multiple timelines, and multiple versions of the same lives. With the help of Sarah’s most troubled patient, they form an unlikely trio navigating shifting realities, fractured memories, and a killer who seems to exist everywhere at once.
Time is folding in on itself. Identities are merging. And every choice they make in one life echoes dangerously into the next.
From the Oscar-nominated screenwriter of "Arrival," Simultaneous delivers:
Stunning reveals and reality-bending twists
A tense, race-against-time serial-killer mystery
A supernatural edge rooted in fate, free will, and the weight of past lives
Characters whose connections deepen across lifetimes
Perfect for fans of early Dean Koontz, Blake Crouch, and mind-twisting supernatural thrillers. If your past is chasing you, how far can you run when it knows your future?
‘A twisty, mind-bending thriller that will keep you guessing until the final gut punch.’ —Leigh Bardugo

Praise for this book
"A twisty, mind-bending thriller that will keep you guessing until the final gut punch." - Leigh Bardugo
"Eric Heisserer's Simultaneous has a mind-blowing premise and razor-sharp execution. Wildly imaginative, emotional, and propulsive--I could not put it down!" - David Koepp
"Past lives and parallel lives, crime and potential punishment--but the most thrilling thread here is facing belief in a wild theory, a worldview changing, as the theory becomes the most sensible one on the table. Heisserer has outdone himself: a novel with the cinematic stakes and pacing as one of his brilliant scripts." - Josh Malerman
