This is the fifth book in the Alpha Pack series. It can be read as a stand-alone, but I recommend reading the other books first. The author does a good job of filling in back stories, but there are several stories that carry, build, and change through the series. I did really like this book, though. Probably my favorite of the series so far. Magic, werewolves, treachery, fighting, and sex mix in a good combination. It’s a good crossover book for moving from regular sci-fi to paranormal romance. The story line is fairly original. I particularly liked the depth to which the main characters were developed – it is very easy to relate and connect to the characters. The author does a great job of building and maintaining character depths, connections, and interactions. I am impressed at how she connects the books and maintains such strong secondary story lines across several books and changes to the story line. She also does a good job of setting up future story lines in a way that makes readers want to read the next book(s).
