Soulless

Generally described as “steampunk”, but with not a lot of steam and no trace of the punk, this is set in an alternate Victorian Britain that has accepted vampires and werewolves into society. Sort of a mid-Victorian True Blood, only with a lot more humour.

The tone is breezy and fun, and the heroine impresses as a rebellious woman who is nonetheless clearly a product of her time and social station. The story is by no means a comedy, although it has its comedic moments, and a great sense of fun, even where some of the characters are sinister or evil.

It's hardly what you'd call “deep”, although it's well written and makes a nice break between more serious novels. The only other Gail Carriger book I've read is the first of her Finishing School series - unlike that, this is decidedly not Young Adult, with much less of the weird tech, rather more of the dark elements, and a romance plot that concludes with a steamy epilogue.
