Infernal Devices (Mortal Engines #3)

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. Wren longs to escape the peace of static Anchorage. She craves the dangerous adventures her parents once had—and a charming submarine pirate is ready to take her to sea.

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 …

Infernal Devices is the third thrilling instalment in the Mortal Engines series by Philip Reeve, continuing the epic adventures of Tom, Hester, and their daughter Wren in a world where cities move and the past haunts the present.
