Predator's Gold — Philip Reeve

TOM AND HESTER ARE IN DANGER

Pursued by the grim aviators of the Green Storm, they stumble onto the ice city of Anchorage just in time. But Anchorage is not a safe refuge: devastated by plague and haunted by thieves or ghosts, the city is barely lurching along. And savage Huntsmen are closing in. Surrounded by danger, Tom and Hester struggle as jealousy threatens to destroy them and the city.

In a desperate bid for survival, the young ruler of Anchorage sets a course for the Dead Continent: America.
