Yesterday I finished Mortal Engines by Philip Reeve.

Mortal Engines is a YA book set in a far future dystopia where cities have become huge mobile machines, travelling around looking for other cities to steal resources from, a process referred to as Municipal Darwinism. When the book starts, new cities to devour have become scarce and the leaders of London have hatched a dastardly plan to use Old Tech to conquer the last holdout non-roaming cities, called the Anti-Traction League.

The story is fun, if very off the wall, but the writing has some issues, particularly with point of view. Generally it follows one character at a time, but at time the author seems to forget where it is and will give us the inner thoughts/feelings of a character in the same scene before returning to it's proper place.
