I think that every good book must have a level or combination of those things. How else do we know that we humans are normal?
I know what it’s like to fall in love, and have a certain level of infatuation for someone else. In your world, nothing else even compares to the emotions that swirl out of control for that particular person. Those moments? They are precious. And just like with real people, when it comes to characters, again – that is a character emotional driver for them to do the crazy things that they do.
Carmen Amaro, the crazy bitch villain in Tijuana Nights, has a certain level of infatuation with Mack. Actually, I think it’s more of a fixation on Mack dying, and Carmen having ultimate control, but it’s still a level of infatuation. Carmen has her reasons though, reasons that are revealed in the book. But her biggest reason is jealousy. She loves her husband, Javier, the leader being the El Diablo cartel. He gives her a level of power over a lot of people, and when Mack walks into Mexico and upsets that powerful little apple-cart by becoming Javier’s new fixation in life, Carmen can’t tolerate that. Not many wives would. Mack on the other hand is just doing her job. Distract Javier enough so that the team can get into the El Diablo headquarters and extract out a huge amount of information of the inner workings and chain of command of the Cartel.
And then everything obviously went pear-shaped, and the book Tijuana Nights came to fruition.
In that book, you have everything that is listed above to varying degrees.
Somehow, I think that’s what makes it work.
