Name for my supernatural series?

I am writing a novel series about light and dark elves. It's an urban fantasy series, meaning it takes place in a real world. If you like LJ Smith, then these are the books for you. The heroin is certainly no Mary-Sue, her love interest is chalked full of dark humour and devilish good looks, and the supporting characters complete this puzzle of misfits. There's passion, whit, and action. The only problem is, I can't figure out what to call the series. Can some one help me out? If I chose your name, I'll give you a shout out in my Author's Note.
