When Emma's brother goes missing while she's supposed to be watching him, she and her new neighbor, Andrea, set out to find him. But what they discover beneath the floor of the old barn defies imagination. Before they know it, they are sucked into the real world of Ranger of the Realms, the same video game Emma was live streaming, or at least trying to, before Jake disappeared.

Together, they embark on a journey through a bizarre new world, hoping to win a game, save a race, and find their way back home.
