The world is dying, overcrowded and polluted. Storms rage over the immensely tall tower blocks, attracted to Movers.

Movers are connected to people in the future, their Shadows. And moving your Shadow is highly illegal.

Patrick knows all too well what happens if you break the law: his father has been in the Shelves ever since he moved his Shadow. And now Patrick and his family are in danger again.

Following a catastrophic event at their school, Patrick must go on the run. Through filthy, teeming markets, forebrawler matches, a labyrinth of underground tunnels and beyond, he’ll need his wits and courage to escape the forces that want to take everything he loves.
