Nature had called to Callie since she was a child, quite literally. The leaves in her grandmother's garden have whistled a song only she could hear, the trees had rustled in the wind calling her name; the bees, the birds, and even the giant oak tree in their backyard had whispered ancient secrets in her ear, about her family, the neighbors, the people of her quaint, little town of Rivendale and even about their vast kingdom of Sarkania.
But, when a mysterious stranger comes into town, Callie's once peaceful life turns upside-down, as she is suddenly thrust into a world she knows nothing about. A world filled with magic, mayhem and unknown, dark forces that threaten to destroy her very existence. Suddenly the fate of the whole kingdom rests on Callie's shoulders- and now it is up to her- whether to fight and protect herself against these forces or let them consume her instead...
