The brilliant sequel to Mortal Engines and Predator's Gold. Anchorage has become a static settlement on the shores of the Dead Continent, and its inhabitants have been living peacefully for sixteen years. But now trouble is approaching - in a limpet sub, and fast. The Lost Boys are back, and they'll do anything to get what they want. Tom and Hester's daughter Wren is their eager dupe, bored and desperate for adventure. When the theft of the mysterious Tin Book of Anchorage goes wrong, Wren is snatched away in the limpet, who knows where. Tom and Hester set off to rescue her, but this is the end of their quiet life on Anchorage. The journey will stir up old needs, old secrets - and send them into perilous waters...
Nearly twenty years after the city of Anchorage settled down on the shores of the Dead Continent of America, Tom and Hester are leading quiet, peaceful lives. Their wild adventures happened so long ago that they seem like little more than stories told to children -- children such as their own daughter, Wren, who is so exquisitely bored that she'd welcome any sort of excitement. . . .
So when a trio of Lost Boys asks her to steal the mysterious and deadly Tin Book of Anchorage, Wren is only too happy to help. But the theft goes wrong, and the Lost Boys steal Wren, too, leaving Tom and Hester no choice: They must abandon their peaceful life and rescue their daughter. Their search will reunite them with enemies they thought they'd left behind forever, will ask of them sacrifices that no parent can make, and will cost one of them everything that matters most.
