Very captivating first book in a series. 
 I enjoyed the dynamic between all the characters, which were highly developed. The story premise was original, fast paced, and imaginative. I have not seen anything close to the Psy in any other book. Even though the Changelings were the same as shifters or weres, they were written well. This book was the epitome of paranormal romance. 
 I have high hopes for the rest of the series. Nalini Singh's series, the Guild Hunter has evolved book after book into greatness, I expect nothing less of this series as well. 
 I absolutely adore Nalini Singh and will read everything she writes! 
 Recommended to those who love:BDB, Demonica, Immortals after dark, Midnight Breed, etc...
