A very non-standard romance, which brings to mind Nabokov's Lolita in that there is a significant age difference between the protagonists (Wavy and Kellen), which sets up much of the dramatic tension in the book. I think the author does a good job of treading the fine line between gaining the readers' sympathies for her characters, but also for the resistance to such a relationship by those around them and society in general. Toward that end the story is told from the point of view of characters major and minor (1 per chapter), which definitely helped hold my interest. 
 I can see how such a topic would (still) be controversial in this day and age, and I could see this book being banned because of it, but I think the individual reader should check it out for him/herself and make their own decision.
