And I can tell you in no uncertain terms that my protagonist, Henry Bell, will not be doing this. For one, he doesn't know the first thing about horses. He does, however, know a lot about swords, and about the choreography of sword fights. You will see him staging realistic fights with this kind of knowledge:
So enough of that. How about jealousy? Will we have some of that between the current enemies who will eventually become friends and even lovers? Probably more of that feeling as the story progresses, than any real romance. Poor Henry is so tormented the first half of the book. He is attracted and repelled by Fae Donovan. Who? Oh, MY, the heroine has a name now! Fae owns Faerie Creations, and though she doesn't really look like fae herself, just the connection reminds Henry of his first wife. Thus, the repulsion. So why should he care if other men are attracted to Fae? Why should he feel deep and aggravating jealousy?
Because, well... is lust every reasonable? No. Is love? No again.
