Now for my breakdown of the guys for romantic book trilogies.
Book 1: Alpha Male aka “The Head Honcho” – Usually in romance trilogies, the first hero is the one of the highest social rank (alpha male of the pack, king/prince/duke/earl, oldest son, leader of whatever group the trilogy heroes are a part of, etc.). He’s the opposite of the more docile heroine he’ll be wooing – more domineering, inflated sense of his rank and never hesitant to put anyone in their place.
Book 2: Beta Male aka “The Second in Command” – This hero is usually the Head Honcho’s wingman or best friend. He’s often also the “good guy” in the trio or the one most honor bound and solemn as a monk. Well, I guess it does take a lot of patience to wear heroine #2 down.
Book 3: Omega Male aka “The Rebel Without a Cause” – The last story often involves the most rebellious, least mature of the trio. Often, he’s the one getting into bad scrapes but he manages to handle himself quite well until heroine gets involved. He is also a thwarted lover, of either one of the previous heroines or another girl from his adolescence or some years before the stories take place. Where he goes, trouble is likely to follow.
