For me - and I love all the books in this world - this was the best since the 2001 original, Mortal Engines.
Thunder City is a vivid - and surprisingly violent - ensemble action-adventure about a plucky group of rebels trying to retake an usurped traction city in the far-distant future of a reshaped Earth.
A postmodern Victorian scientific romance, peppered with sly jokes (the one about a certain tourist attraction in Paris made me laugh out loud) and cinematic references, as well as the usual rich assembly of engaging and interesting characters, Thunder City was a blast from start to finish.
The ending certainly leaves the door open for more stories about the protagonists and I just hope we don't have to wait quite so long for our next visit to the World of Mortal Engines.
