The Miseducation of Miss Delilah

I've read a couple of Maggie Dallen's books by now that feature one of the “mean girls” as the heroine - and I enjoyed each of these stories a lot.
Haughty, arrogant Delilah turned out to be another surprisingly likeable leading lady, and her verbal sparring with not-quite-your-average-dashing-nobleman Rupert was so much fun. :)
This story is not quite as light and fluffy als Louisa's, and Lord Evil makes a dastardly return, but it's still an entertaining and swoon-worthy read with a fitting HEA.
