This category has a clear winner - White Cat, by Holly Black. The world in this story is just something I've never heard of before - curse workers, who can subject you to bad dreams or broken bones with just a single touch. But they suffer 'blowback' every time they work, and what's more, curse working is illegal, so they're all criminals and the world wears gloves to guard against them. It's just such an intriguing, unique premise. Fantasy is meshed with the real world, and while this has been done many times before, the results here are gorgeous and dark and definitely unique.
