I received this book from PaperBackSwap.com on the suggestion of a friend who seemed to think I would like the series because I also like the Black Dagger Brotherhood Series. I can't say I hated this book or that I'm not interested in the series. I do plan on reading the rest but have to admit that I'm not completely in love with the series at this point. 
 Admittedly, I wasn't all that enthralled by the first book in the Black Dagger Brotherhood Series either but as the series went on it got a lot better. I'm hoping that is the case here and as I've read the first 3 chapters of the second book, I believe it will be the case. 
 Adrian is a good writer. There is nothing hard to understand and her vampire lore, while different than most, is intriguing. According to Adrian, her vampires are an alien race (much like Ward). The biggest difference is that the Breed (as the are called) were violent aliens that came to Earth and discovered they needed blood from humans to survive. They are responsible for whole civilizations dying out (ie, Atlantis and Mayans). 
 It was upon discovering the Breedmates, woman with the birthmark of a tear drop and crescent moon, that they realized they could breed with humans. The offspring of such unions are always male. Lucan are hero is the result of such a union, making him and extremely old vampire. He also abhors the violence of his race as do most who have vowed not to give in to the need for blood but rather only take what they absolutely need. 
 Lucan with the help of some others are Breed Warriors. They kill those vampires who give into the Bloodlust and kill indiscriminately. 
 I did like that the Breedmates seem to feel like the are different than others. They seem a little distant from the rest of the humans and also seem to have special gifts as in the case of Gabrielle who is a genius with a camera but who seems to pick out the location of Rogue Vampires with her shots. 
 One of the things that got me about this series is that it surprises you. Normally when you are introduced to a cast of characters it is highly unlikely you will lose 1 or more of them. In the first book there is a small shock and one I didn't expect. Also, while Adrian leads you on the trail of who the possible traitor is she leads you astray which was unexpected and great. 
 I would say these are interesting books that I am enjoying but I don't think I will be keeping them. I've already managed to swap this book with a gal who really wants to read it.
