I was hesitant to read this book because I have never really been a fan of Mencheres. But of course it's always different when the story is told from their POV (as opposed to the Night Huntress series told from Cat's POV). 
 It's been so long since I've read the Night Huntress books I can't quite remember where it fits into the series itself but Mencheres, after more than four thousand years living, want to end it all. His visions of the future have ceased to come to him and he sees this as a sign that it's time for him to end it. He is in pursuit of doing this very thing when Kira comes upon him. She hears the fight Mencheres is in with a group of ghouls and assumes it is a normal person needing help. When she come upon the fight she is mortally wounded and Mencheres decides to save her life. So his original plan is put off course. 
 He is immeditaly captivated by Kira. One of the reasons being that he can't figure out why he can't read her mind of influence it. The reason for this is never explained. In fact, one of the things for me, that was sort of just thrown in the mix but never really addressed is the fact that Kira appears to be an empath. She can sense emotions. We don't know if they are just emotions of those she is closest to or everyone. It appears it's only those she's closest to because one of the people she "senses" is her sister Tina, who has a long-term illness. I understand an author not spoon feeding everything to a reader, letting us come up with our own conclusions, but I thought that throwing it in there without even other characters commenting on it was rather strange. 
 It's not too difficult to figure out where the story goes. There is a main conflict that Mencheres has with another vampire, plus he has to work out his feelings for Kira, along with his own feelings of ending his life. 
 I liked the book more than I thought I would and I liked that it filled in the rest of the Night Huntress story up to this point. It's still one of my favorite series and I enjoy the side stories with secondary characters. You don't necesarrily have to have read the main series in order to pick up this book. So if you are interested in the author you could very well start here to get an idea of the writing.
