Another +1 to the rec for Carriger's Parasol Protectorate series. They're lots of fun as a spoofy alterna-Victorian parody and it's a complete series as of the 5th book, so you won't have to worry about dangling storylines. They're definitely primarily steampunk society adventures, but there's strong romantic elements in the 1st book and plenty of shippy stuff throughout them all (at least up through the 4th book, which is as far as I've read).
Here's my
impression of the 1st &
2nd book from last year, plus some follow-up comments from other people who read the 1st in the Reading Recs forum, if you're morbidly curious.
