The sexuality in the book is going to be a problem for some and rightly so. However, the effort to give the author a chance to explore an alternate idea of life is integral to the sexuality as a bridge. Exploration of sensory guides can come to an author in different ways. Patric Rothfuss used sensory portraits to explore a lifeform in The Slow Regard of Silent Things. A difficult animation was attempted in The Alchemy of Stone by Ekaterina Stevens. The sexuality in this book is about the challenge between life and death. It is a fair thesis for story telling and the use of explicit sex to drive the desperation between the two dimensional notions perhaps the most universal experience for this problem. Personally I may think the author used the sexuality with more license than needed. It was not my story or my notion of sexuality and the point of the story is actually made. It is fantasy and when a point is made through fantasy there should be applause.
