I don't know what it is about these books but I am glued to every word, (and I have only read 2 books in this series so far.) This is Rhage and Mary's story. I was interested in reading more about Rhage and his other half, and I'm talking about the beast not Mary. :) I was not disappointed. And we also got a little peek into Zsadist's mind and find out he's not exactly what he pretends to be. But he is damaged and I can't wait to read his story, which seems to be the most popular one. I think I liked this book better than the first one because I already knew the basics of the story, such as what doggen are and what a Shellan is. I had to pace myself because I wanted to read it really fast so I could find out what happens next but I also wanted to savor it, so I had to find an "inbetween". Bottom line: I loved it!
