The basic concept of this book is a half angel and a demon have met and fallen in love to the disapproval of both of their families. The characters are determined to find their own way turning their backs on families and tradition.
The basis of the story is very old and if I follow it to it’s conclusion I hope it doesn’t emulate entirely the Romeo and Juliet plot line.
There is a heavy emphasis on their looks, each being the embodiment of perfection for what they are, literally a full bodied angel and a lusty demon. I understood that she was depicted as beautiful and he masculine, strong and handsome after the first few pages and didn’t need a constant reminder that the author felt necessary. The author also explains to the reader that she is both physically and emotionallystronger than he, but she chooses to submit to him out of love. She could at any point use her safe word, or her physical strength to stop or even destroy him, but only once is even temporarily tempted to use her safe word.
Angel gives of herself and thus by doing this opens herself to being more than she has been and binds her lover to her in stronger ways than if she were a traditional lover to him. Much is made that he has numerous lovers, but she is the first and only one to give so deeply of herself.
The BDSM portion is strong and sensual, although portions probably don’t contain enough descriptive language for many. The author referencing the brief biography given is normally a writer of Romance stories, I think this shows in her setting up a scene and then passing over much of the explicit BDSM sex quickly.
