Title?

I've been marinating on my query letter to send out to agents. I'm actually feeling pretty good about the summary and hook that I've written about my book. It's my title that's tripped me up.

The working title has been a phrase that I keep saying when I've described it to a few people. So, to me, that's what the title has been. But, now that I've written the query letter, it doesn't quite seem right. So, I've been trying to brainstorm other possible titles. I've teetered from one to another, not completely embracing any one thing. Should it be foreboding? Poignant? Intriguing? Catchy? Each, to me, has a different flavor. But all do connect to the main characters and storyline. It's tough.

I realize that no matter what I choose right now, it could change - in the happy event that it does get published. But I do want it to be it's own tag line of sorts. I want a title that would make anyone curious when they hear it - especially an agent or publisher. So, I'll keep working on it, but I really want to get the ball rolling and start sending out letters and see what happens!
