Human Cooper Dayton and his werewolf boyfriend Oliver Park are engaged and beginning to plan their wedding, which is stressing Cooper out- not least because his family, who he didn't talk to much for a couple years, are being very supportive and it's weirding him out. Also, the chaotic scientist who threatened to expose the werewolf community and then turned herself in to werewolf government asking for a deal is making vague threats about enemies Cooper doesn't even know about. Then a body is discovered at the DC zoo, a werewolf killed and frozen in a half transformed state- nothing that the werewolves have ever seen before. I am still very entertained by this series as a whole and glad I listened to all of them, but I did want a little more than this book delivered on mysterious enemy front. There was a conspiracy, but it wasn't as far reaching as I was lead to believe by the cliffhanger ending of book 4. However, if you are reading these books more for the spicy scenes and romantic plot line, you won't be disappointed.
