I liked Her Dark Angel. I kind of expected to see more conflict to pull Apollyon and Serenity apart, but not having my expectations met in this instance wasn't a bad thing--at all. This book was short, so there wasn't a lot of time for world building, but that's okay. There was enough. And the sex was fun.Her Dark Angel was a free Kindle book I downloaded on September 5, 2012 for the Why Buy the Cow? reading challenge.
