I slink out to the hammock with a tablet and stay there until I've compiled a list of 15 titles. Anything that comes to mind can go on the list. Then I trot back inside, type up the list, and blast it out to my closest friends and family. They pare it down for me.
The truth is I'm TERRIBLE at coming up with Titles. Encapsulate my entire work into an eye-catching 3, 4 or 5 word phrase? Also, you should google your title on Amazon to be sure it hasn't been a best-selling title recently. (Although a title can't be copyrighted, so you're free to re-use someone's).
In truth, a title is very closely related to that thing we were taught in high school English--THEME. It makes us uncomfortable to talk about theme. Most of us had high school teachers who slapped us with a D on the paper and wrote "WRONG" across the top. I graduated from college during a time when something called reader-response theory was in vogue. If you read it, and your response is genuine, then your ideas are valid.
I often tell my college students that the theme of a story is the meaning minus the specific character names. It's over-arching like an umbrella. Our title should suggest or tease that theme. Choose carefully, then enjoy the fun part . . . planting it deep in the story.
Lucy realized they would all continue to take the risks they needed to take,
pay the price required of them. They would do it for the people they cared
about. So Dayton, and any other children coming into this circle, could grow up
in the country they loved. Living without love was something she wasn’t
courageous enough to do. The cost of love? It had always been, would continue to be, high. Gazing across into Dean’s eyes, she’d wager love was worth any cost.
