Heavenly Deceit-- Books 1 & 2

Willow was fourteen when her mother died of leukemia, leaving her relatively alone. She goes to live with her three older brothers in New York, but on the plane ride there they get taken magically to a place called Eden, in which all of the residents are either dead and decomposing in the streets, or asleep in the castle Sleeping Beauty style. They soon learn that Eden has been dominated by a virus, and the only way to stop it is for the new king or queen to be crowned. In order to save all of Eden, Willow and her family must undergo a series of nearly impossible tasks in which the penalty of non completion is death. Can Willow and her family complete these task to save all of Eden? Or will one of them be the one true king or queen, and rule over all of Eden? And what comes next?
