Earlier editions in this series seemed to focus on weird and unusual sex. This one, the relationship was the main focus. Two characters with low self esteem - the H because of a learning disability (Zetithians can be dyslexic? Interesting), the h because her father has browbeaten her into thinking the best she can hope for is to take advantage of the H's stud services and run away. Fortunately for both of them, she's his mate, so he gets to spend the rest of the book attempting to convince her of that. Add some disreputable men who are specist, a man from a species where women often have two husbands, a few pterodactyl-like beasties, plus the usual cast of aliens (but no Jack, thank you.), and he has his work cut out for him.
