Harper Starling has spent three years stuck in grief after her best friend, Peggy Mara, disappeared without a trace. Then Peggy returns—scarred, altered, and speaking like a stranger—hunting a carved harmonica that can “call a man” across the stars. The man turns out to be Miles, the real-life inspiration behind Harper and Peggy’s beloved retro sci‑fi show, Infinite Odyssey, and his vintage muscle-car “Tesseract Engine,” Argo, can slip through time and space.
Dragged into a chase that spans 2023 Harlem, 1970s New York, and distant alien worlds, Harper learns Peggy has been taken over by the Incarnate, a planet-devouring psychic parasite born from Miles’s ruined homeworld. To rescue Peggy—and keep Argo out of the hive’s hands—Harper must confront her own rage, change the past without breaking it, and discover what kind of love can starve a monster that feeds on hate.
