London is a radioactive ruin. But Tom and Wren discover that the old predator city hides an awesome secret that could bring an end to the war. But as they risk their lives in its dark underbelly, time is running out. Alone and far away, Hester faces a fanatical enemy who possesses the weapons and the will to destroy the entire human race.

The mighty engines of Anchorage have been rusted and dead for years. The derelict city no longer roams the Ice Wastes, but has settled on the edge of the land that was once America. Tom Natsworthy and Hester Shaw are happy in the safety of a static settlement, but their daughter, Wren, is desperate for adventure. When a dangerously charming submarine pirate offers her a chance to escape, Wren doesn't think twice about leaving her home and her parents behind. But the pirate wants something in return - Wren must steal the mysterious Tin Book.
