Aside from being ridiculously fun and entertaining, the most amazing quality of The Black Lung Captain is that it is an even better book than Retribution Falls. Chris Wooding has taken pretty much every element that made the first novel great and kicked it up a notch. An impressive feat.
The characters that populate this novel have definitely reached that point where they stop feeling like characters and more like old friends. Wooding wasn't content to just rest on the character development he had in the first novel. Instead he added more layers to each member of the crew, and further fleshed out their past, and their inner feelings and demons. Wooding also develops a few side characters as well, which makes the story feel bigger, and gives the reader the sense that the events will have ramifications that spread beyond Frey and his crew.
Another quality of The Black Lung Captain that I love, and the same goes for Retribution Falls, is how much fun these books are. Wooding has found the perfect balance between action, characters, plot, humor, and drama. It all magically comes together to make one fantastically great read. I really think a book this fun and this engaging is a rare find, yet Wooding has written two gems so far.
I do however, have one gripe. Maybe it's the fantasy lover in me, but I really wish there was a map included here. Only because I struggle with the scale and distance of places. I don't know how fast the airships can travel, so it is hard to judge how far away places are or how big the land is they are covering. This little gripe doesn't really do anything to decrease my enjoyment, I just wonder about the mechanics.
