If Ruby Wright could have her way, her dad would never have met and married her stepmother Willow, her best friend George would be more than a friend, and her mom would still be alive. Ruby knows wishes can't come true; some things just can't be undone. Then she discovers a tree in the middle of an Ohio cornfield with a wormhole to nine alternative realities. Suddenly, Ruby can access completely different realities, each containing variations of her life-if things had gone differently at key moments. The windshield wiper missing her mother's throat...her big brother surviving his ill-fated birth...her father never having met Willow. Her ideal world-one with everything and everyone she wants most-could be within reach. But is there such a thing as a perfect world? What is Ruby willing to give up to find out?
