Family—can’t live with them, can’t kill them. It seems to me that family is the cradle of our profoundest emotions: love, tenderness, jealousy, anger, envy, and, yes, hate. No one can make us feel as cherished as family. No one can hurt us as badly as family.
Because of that, writers mine family for motivation and internal conflict continually. What is the source of your alpha hero’s angst? Dig into his childhood. Blame his father…or his brother. Why does your heroine believe she is unlovable or incapable? Check out her family of origin. What makes the villain tick? I’m willing to bet it is family or the lack thereof. Heroes and heroines each come from a different family culture. In the end whether it is happily-ever-after or happy-for-now, they are creating a new one. We cheer them on and hope for the best possible future.
