Simultaneous by Eric Heisserer

Have you ever had a premonition? That strange feeling that something is about to happen—a ripple in the fabric of the day that only makes sense once the moment arrives. For most of us, it’s fleeting, a quiet echo we don’t fully understand until much later. But for a small handful, it can be something much more profound. Federal agent Grant Lukather knows this better than most. As part of Homeland Security’s secretive Predictive Analytics branch, he’s spent his career tracking subtle patterns and statistical anomalies to prevent the unthinkable before it happens. But when a call comes in about a possible explosion in New Mexico, Grant finds himself caught in an event that will shatter everything he thought he knew about premonitions, and about fate itself.

That investigation leads him to Sarah Newcomb, a therapist who practices past-life hypnosis and has recently stumbled onto something that defies logic. Soon, Grant finds himself drawn into a web of murders spanning multiple states and timelines, where memory, identity, and consciousness begin to blur. With Sarah and one of her patients by his side, Grant races against time to stop a threat unlike anything he’s ever encountered. 

When I heard that Eric Heisserer, screenwriter of the hit film Arrival, had written a novel, I knew I was in for a treat. Simultaneous proves that instinct was correct. Heisserer blends high-concept science fiction with deeply human characters, delivering a tightly paced thriller that hooked me from start to finish. In Grant Lukather, Heisserer creates a skeptic whose doubts mirror our own. We experience discovery alongside him, watching disbelief shift into wonder. It’s a smart, cinematic read that delivers both heart and high stakes without ever overstaying its welcome. For fans of grounded sci-fi with big ideas and emotional depth, this one’s not to be missed.

  8. I am not surprised a screenwriter wrote a great novel. I think they understand the way people like to consume certain things. The blend of sci-fi and humanity is intriguing to me.
