I got confused. I mean it is about an Incubus so I got that, but the whole Landscaper and Bridge thing started throwing me off. It is very fantasy which I don't have a problem with but I was very confused. I mean the love story part took no time which bothered me and they didn't seem to resolve anything which I think is the point because it is a series (I think). 
 I can't say Anne Bishop is a good author. I wasn't found of her writing but the story interested me enough that I actually went through the entire book. I got that the gist of the story was that the world isn't like earth but rather magical lands called Landscapes that are connected by bridges. There are lots of magical beings including Sebastian who is an incubus. The Landscapers are woman who can control the Heart's Desire of Humans which manifest in the Landscapes. This insures that everything a Human thinks up doesn't manifest. The Bridges are men who can connect worlds via bridges. 
 So the idea is that a great evil is loose and threatening this magical world. It ends up killing all the Landscapers and Bridges except Lee and Glorianna who are brother and sister. Glorianna is a rogue Landscaper because she is very very very powerful and the evil wizards wanted to cage her (basically). Lee is loyal to her and a powerful Bridge but it is up to Glorianna Belladonna to save their world. 
 This story is about Sebastian who is their cousin and thinks himself unworthy of anything good. He lives in the Den of Iniquity like lots of other Demons. Lynnea lives with who she sees as her parents though we learn she was most likely stolen as a child. They treat her badly and all she wants is someone to love her and to love. She ends up going to the Den because she is drawn to Sebastian and bang they fall for each other... which is not even the story. I was happy these two had each other but the story was supposed to be about them.... Wasn't it. I don't think this was the best story but I'll probably read more of the series when it is available.
