College freshman Silas Turner is a scientific anomaly. Thrown back in time uncontrollably, he’s forced into his pre-transition body for hours to days at a time, reliving random events in his past. Why? Every cell in his astrophysics major brain is straining to figure it out. But the “time trips” just keep on coming, disrupting Silas’s life, and he’s certain he’s a one-of-a-kind phenomenon - until brash, guitar-playing Jude Forrester barges into his life, exhibiting the same symptoms. He claims a future version of Silas visited him, and that, according to future-Silas, they’re meant to help each other stop the time trips. If working together can really lead to finding a cure, Silas can handle Jude’s tortured-artist attitude; Jude can humor Silas’s nerdy obsession with the stars. As they get closer to a solution, they grow closer to each other. But Jude is still grieving an old connection that broke his heart, and he can’t help but wonder if changing the past might save himself and Silas a lot of heartache. Amidst cataclysmic consequences, Silas and Jude must face the cosmic circumstances that brought them together if they hope to protect their timeline - and the future they seem destined to share.
