There is a line from Nightswimming, from the Freebies and sExtras page on Tiffany Reisz's website that is very appropriate for The Siren. Nora says to Wes: "Clearly I need to educate you on the finer points of the kink universe. The rules are very different there." The Siren shows that she isn't kidding.In The Siren, we get a long glimpse of this universe. This is not an erotic romance, although it might be a love story and its definitely a romance according to the Oxford dictionary. You will be taken to a world that is mysterious, exciting and remote from everyday life. Not every reader will like be comfortable there. It lets you peer over the edge into a world that is unlike what most people experience. It will make you think and question. That's the beauty of this book. The characters are multidimensional and defy being simply labeled "good" or "evil". Nothing is easy about this story, and that is a very good thing. One of my favorite aspects of The Siren is the way Ms. Reisz uses theological concepts throughout the story. The themes of absolution, sacrifice and obedience flow in the words and deeds of the characters. Very nicely done is a respectful manner. So overall: The storytelling is compelling and well crafted, the characters are multidimensional and interesting, the writing well done, and there are enough loose ends and questions remaining to keep my interest to continue the story. I'm very much looking forward to seeing a more complete picture over the upcoming installments of the series.
