I used to watch NCIS...until I realized Ziva and DiNozzo weren't going to hook up.
Turns out my real interest lay in the tension between these characters, and when their attraction seemed to take a backseat, so did my attention. I still like the show, but it no longer hooks me.
Sometimes what one person loves in a story is completely different than what someone else loves. Same story, different draws.
This is why it's so important that we have more than one hook in our books. Every plot has more going on than just action, or just romance. My husband's favorite movie is Braveheart. He loves the action. That's his hook. Mine is the lost love, but also the new love with the queen.
What is your fave book of all time? Why? What is it about that story that hooks you? Do you have more than one hook in your WIP?
