(Oh, and Beauty Queens by Libba Bray is really good, too)
Uglies, Pretties, and Specials by Scott Westerfeld (though not Steampunk or Victorian, they are good) and his new books are decidedly Steampunk. Will be starting them soon, once my mother (yes, my mother) is finished with them.

Books by Amanda Quick (pen name for Jayne Anne Krentz) are decidedly Victorian (and deliciously Gothic) and I love them all. Though these are written for an adult audience, I will let my 15-year-old daughter read them after me; there is adult content, but it is limited. These are not steamy romances, and the quick witty repartee between the heriones and heros is the best ever!) Check out her Arcane Society novels (my favorite favorite).

Just discovered the author Gail Carriger. I've read Soulless and am starting on Changeless. In the Parasol Protectorate Series, she combines Victorian London with the paranormal (vampires, werewolves, etc.) in a unique way that actually makes sense! Again, these are written for an adult audience, but there isn't really anything in it I wouldn't let my 15-year-old read (though she might aquirm a little :) ).
