If you haven't read from this series before, READ "THE FAIRY GODMOTHER" BY LACKEY BEFORE READING THIS NOVEL
First and foremost, I truly struggled to connect with the main character, Bella. For the majority of the book, she appeared to be haughty, self-centered, controlling, and downright sassy (which, granted, isn't always a bad thing). Lackey may have intended for this to be so, for the character does improve over time. Furthermore, this disconnect may solely be personal, so don't let this be a major deterrent.
Secondly, potential romance and relationships remain a mystery throughout most of the novel. This didn't bother me, personally, yet others may find this frustrating. This mystery doesn't allow for much romantic growth, and the consequential relationship seemed a bit rushed, as if Lackey ran out of time. But again, not a major deterrent.
I did find this book entertaining, yet not Lackey's best work.
