I just finished this book, and I have to say I think it's a winner. I'm going to go through the bad first, and then gush. :)
The bad: There are some spelling/formatting errors scattered throughout the text which I found distracting. Most of these are of the 'spell check reads it as ok, but it's really not' variety, such as using your instead of you're and so on. I'm a bit nitpicky when it comes to my books, and proper formatting is a must. It throws me immediately out of the story and makes me reach for my red pen.
In addition, and this is *personal preference*, some of the sex scenes were too short. HOWEVER! That being said, there are a lot of them! For the most part, they are very well written. I just wish there was more? Can that be a bad?
The good: The plot was very intriguing and MADE SENSE. Yes, of COURSE it makes sense Maeve fucks guys to see if they are the champion. It's a perfect set up. And yes, of COURSE she's open to sexual relationships--she's a faerie! Not only that, but I really loved how Reed touched on polyamory, which is something that isn't discussed a whole lot, and how it's loving people with permission of your partner. Such a great way to put it!
This is, of course, a plot heavy book, but the plot doesn't move that much, at least not initially. I would basically put it as the first act of a first novel of a trilogy. This is the Heroic Set Up where we find out who the hero is, and actions begin to brew to move against our hero. I also liked the parallels drawn between Summer and Winter, but as I read further in the series, I hope that the capriciousness of all fae--at least according to mythology--is highlighted, and how alien they can be. Of course, since it's the first book, a lot of the plot did deal with the set-up and worldbuilding, and I'm perfectly happy with that.
The sex was pretty hot, and it was plentiful. As I mentioned before, some of the scenes were short, but that's a personal preference. I would rate it 4.5 stars (I always round down when it comes to ratings), and if the formatting errors were fixed, I would probably bump it up to a five.
