Simultaneous

Written by Oscar-nominated screenwriter of Arrival and creator of Shadow & Bone — marking his debut novel.

Federal agent Grant Lukather works for a secret Homeland Security division called Predictive Analytics, using tips and chatter to prevent terrorist events before they occur. A tip about a possible explosion in New Mexico triggers an investigation that leads him to Sarah Newcomb, a therapist who practices past-life hypnosis — and who recently uncovered a phenomenon that defies logic. 

When Grant and Sarah follow this clue to a copycat killer case in Colorado, they realize the investigation spans multiple states, timelines, and consciousnesses. Racing against time with only tenuous clues, the unlikely duo — and a hesitant third collaborator — must unravel a conspiracy that threatens lives in the past, present, and future.
