A review by hartstrings
Predator's Gold by Philip Reeve

4.0

Hester and Tom have been living the high life on the airship Jenny Haniver. Fortune takes them to the city of Anchorage on the Ice Wastes. Freya, the last of the royal line of rulers, delusional-y steers the city towards the American continent in search of a lush green land spoken of by Professor Pennyroyal. Ooh, plus we run into some Lost Boys.

Fun steampunk vibe. I still love the traction city idea.
