One of my favorite authors right now is Cherie Priest. I am in the middle of two of her books (one I'm reading with Benjamin and one on my own) and there is another one due out at the end of the month or beginning of next month. Since she writes in a lot of different genres, I can't really describe her as having one style. But she writes really good female characters and snappy dialog, and plain, old, really good stories. The most famous series is the Clockwork Century - Boneshaker, Clementine, Dreadnought, and coming soon, Ganymede. They are set in an alternate history where the Civil War is still being fought in the 1880s, and Seattle is infested with zombies.
This cover is from the one that just came out on Tuesday, a sequel to Bloodshot. It is also set in Seattle (at least partially), and has vampires (who definitely don't sparkle), a ex-Navy SEAL drag queen, and lots of action.
Anyway, you should go read something of hers. You will thank me.
