The return of this foe has been changing things badly. And Robin just so happens to be one of them. What happens when Maria can't even recognize the man she loves? Who will help her save the valley once more? And just what does this dark individual want with her? On top of it all Maria realizes she has more powers than she knew and they are beginning to wield out of control. How will she learn to control them when she is the only one who possesses them? And someone near to Maria has a closely guarded secret that could change everything. Will they admit it and risk being shunned or cast out? Or will they hide it forever and watch the valley be destroyed?
