Retribution Falls, by Chris Wooding, is very unique, While most people write off the steampunk genre as too fantasicaly and childish, lacking the elements of a decent book, I found Retribution Falls to be suprisingly good.
Darien Frey is the down-on-his-luck captain of the Ketty Jey, a rather pathetic airship, always on the verge of collapse. Frey has had more than a few misadventures, such as nearly dying in the Great War, and several failed attempts at piracy, but he and his crew always mange to pull through. But when a ‘wispermonger’, a keeper of a vast network of spies and informants gives him a chance to reverse his fortunes, he jumps. Soon what started in a simple robbery turns into a huge conspiracy, with Frey set up to take the fall. Hunted by the authorities, the royal family, and almost every person between, Frey will need more luck that ever to not die in several unpleasant ways.
Fast-paced, funny, and with a deeply interesting history Retribution Falls is a tale of the skies, piracy, near-scrapes with death, and other forces much more dangerous. I would recommend it to anyone, even if they have never read a steampunk novel before.
