He fell into his own life. Someone else was already living it.
When fifteen-year-old Sheffield sneaks into his father's lab and steps inside a chamber he was never supposed to touch, he doesn't just break the rules. He breaks reality.
Pulled across the boundary between worlds, Sheffield is stranded in a future where nature has been almost entirely erased, time travel is regulated like a controlled substance, and a death cult called T.I.M.E. once brought civilization to the edge of extinction. The man who looks exactly like his father is a stranger. The girl in the lab is hiding something that could destroy everything. And somewhere in a prison built outside of time, the man who started it all is still watching.
Back in Sheffield's world, someone is living his life. Going to his school. Sleeping in his bed. Calling his parents.
He has two days to find his way home.
If he can.
