No one's found anything new? Well, I can offer one more tip for readers out there; watch for the "just glue some gears on it" mentality. Steampunk books are quickly getting brass and leather cuts outs, trying to convince readers that they're authentic.
And on a mostly separate note, the "Leviathan" series is one that's gotten a lot of attention. On the one hand, I know the first book isn't exactly bad. However, it is most definitely for a teen audience. This means that it fails to deliver on a lot of the really visceral moments that should be in a WWI book. So if you want something that's light without a lot of calories, it's good for that.
