I've read and reviewed all five books collected here separately, so this is basically just for my own records. The collection rating is an average of the individual ratings, and not a very difficult one at that. Basically, all of the books earned 3 stars from me, with the exception of Heartless, which got 2.5 rounded up to 3 because Goodreads does not traffic in half-stars.

Look, it's a fun series. Absolutely undemanding, but you know, not everything has to be a challenge to consume; sometimes I just want literary popcorn. Light and fluffy, and this series absolutely succeeds there. It's also got interesting world-building and a very strong cast of secondary characters (who are frequently more entertaining than the protagonist, herself likeable enough). The tone is for the most part amusingly flippant, though this does upon occasion get pushed to the ridiculous and undermines any attempt to take more serious plot points seriously. The biggest problem, for me, was the romance. (The first book's really the only one I classified as "paranormal romance", although the relationship continues throughout.) I had the same problem with Carriger's Finishing School prequel series. I seem to find her romances terribly unconvincing. Still, I just rolled my eyes and went on with it, because the books are likeable, frothy fun even so.
