Ariana's life is already pretty difficult when she starts to hear the singing – her mother suddenly disappeared, she's trying to get used to living with her aunt after bouncing around a series of foster homes, and she's taking a lot of grief from the clique of "in" girls at school. But she's also dealing with these sudden premonitions about the future, things seem to get weird whenever she touches water, and now someone, somewhere is singing to her. Soon, she's met the famed Lady of the Lake – who turns out to be an ancestor – UNDER Wascana Lake, has acquired a nerdy sidekick, and is sent on a dangerous mission that pits her against otherworldly forces. Can she figure out what it all means, much less survive the challange?
