YA novel "Six Kristens"

Six physically identical 13-year-old girls with different personalities have no idea how they ended up in a dreamlike fantasy world together, much less how to get home. Almost the only thing they know is that each of them is named Kristen…unless only one of them is real. Meanwhile, two families caught in a devastating natural disaster race against time to learn the fate of the man who may hold the key to a mystery involving life, death and something in between. By native Leesburg author James Dawson. http://www.amazon.com/dp/B00JX44JJM
