When the government rolls out a new tracking program, Matt's family and three others know it's time to run. To leave everything behind and flee north, to an abandoned mansion in the mountains left to them by Matt's grandfather, Elias.

But this is no ordinary mansion. Like Elias himself, the towering halls hold many secrets. As Matt, Luca, Bennet, and Nolan explore its mysteries, they uncover something terrifying: this is not just a safe house?it's a training ground for warriors.
