It was ok, but not as good as some other sci-fi smut that's out there (i.e., Ice Planet Barbarians or author Jaid Black). There are no fated mates, no clear plot, really. It has a lot of threads of where it can go, but it never quite goes all the way, and it doesn't end very well at all. There is no real satisfying conclusion. The two main characters, Alice and Nighteko, are not fated mates, but they fall very fast, and with no real character development, it is hard to see why they do. I like insta love and fated mates, etc, but this was not done well at all, especially for the page count. It's not a bad page count for there to be no real plot or character development. I bought (for like .99 cents on sale) the 5 book collection, and I do t think I will be reading the rest. Also, there is no real smut. It's not really described, and in some cases, it's closed door, so I don't really know the reason for this to exist.
