What's in a name . . . . alot

I know this is premature, but I am beginning to mull over titles for my next book. But what to name it. Pint Sized Partisans was a working title, but I was told it wasn't catchy enough. How do you capture the essence of a book in a handful of words. In that handful how do you create instant interest? Wow this is a hard one. If you have any ideas I'm more than willing to listen.
The book in a nutshell if the fictional prequel to Broken Birds. It's about a young girl who is a partisan in the forests of Poland. She comes of age, falls in love . . . blah . . . blah . . . blah. I can't tell you everything, you wouldn't want to read the book.
