The end of the third book does nothing but leave you hanging waiting for a fourth book which is not coming. The two main characters are a total disappointment. When they first meet the male character says she is the most beautiful woman he has ever seen. They then spend 2 months alone on a space ship and all that occurs is a daily training regimen. There is no mention of any sexual relationship whatsoever. I guess the author refuses to write about realilistic adult relationships. The male lead complains about being homesick and missing his parents. Maybe that’s why he never makes a move or even thinks about intimacy with the most beautiful woman he’s ever seen. I guess the book is geared toward young adults. We should have been warned if this is the case.
