Time Traveler's Theory of Relativity

12-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom vanished with no explanation. Finn clings to the concrete facts in his physics books — and to his best friend, Gabi — to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time.

Finn's mom is trapped somewhere in the timeline, hoping to save his sister, and she's left Finn a portal to find her. Now it’s up to him to travel through time and multiple parallel universes to save them. Your young readers will adore this incredible journey through time and space as Finn and his best friend Gabi break the laws of the universe in order to reunite his family.
