What is Mortal Engines about?

Many thousands of years in the future, Earth’s cities roam the globe on huge wheels, devouring each other in a struggle for ever diminishing resources. On one of these massive traction cities, the old London, Tom Natsworthy has an unexpected encounter with a mysterious young woman from the wastelands who will change the course of his life forever.

Does it have a happy ending? (spoiler-safe)

It leaves things open rather than tying them up.
