Ronnie, a police lieutenant tiger shifter, and Josef, a very old vampire, meet one night when they are both attending a Halloween festival. Even though both were supernatural beings in the same city, they had never had a reason to meet. The flow of their meeting and mutual attraction really seemed to be organic and believable. The romantic side of this relationship was lovely and as sweet as one could believe between a shifter and a vampire.The crime that led to them meeting was both a good reason for them to meet and was one that would lead to them seeing each other in a competent, similar interests way. The pacing of how the crime was found out and solved kept me interested in that as well as the romance.All in all, I think this book could be read as a stand-alone by a reader new to this author. It also is great for those of us who have read all of this author's supernatural books.I have yet to feel that any of her characters are repetitive in nature even if the same types of paranormals are in the book. The couples are all unique in several ways, which keeps me coming back to read each book.
