I love the book Gone with the Wind (the movie too, for that matter!). Without a doubt, Scarlett O'Hara is one of the most memorable heroines in English literature.
Why do I love Scarlett? Well, she's beautiful, clever and sought after. She's also flawed. She's willful, stubborn and selfish. But she's also determined and loyal. Yes, loyal. It is her unswerving loyalty and faith in her love for Ashley (even in the face of the dashing and much more suitable Rhett) that makes her wrongheaded and unrequited love tolerable, and even endearing.
Love should be courageous. Just like Scarlett.
