Christmas. It's supposed to be a time for peace, love, and goodwill to all men. But not for two women when it comes to nabbing the solo spot in the big Christmas concert. To get that spot, they'll do whatever it takes...

Carolyn Roche and Saoirse Barrett have known—and hated—each other for a long time. Their lives have been dedicated to one-upping each other. Carolyn has worked hard to shake off her poor roots, landing a top job at a major accountancy firm. Saoirse has worked just as hard to set up her own business in the vain hopes of impressing her tough father.

They're equally matched in life—and in vocal talent. But neither is willing to let the other woman win.

That is, until they find themselves trapped in their old school, with just a bottle of vodka and their memories for company. There, they discover that the hatred they feel for each other might not be hatred after all...
