And when Raine discovers that the orphans are trying to protect a legendary, mysteriously powerful tree on the premises, she knows that it is her destiny. As the environment plagued with earthquakes and a forest fire continues to decay, Raine uncovers a web of murder and betrayal that dates back to her parents' deaths, forcing her to decide if she has the inner strength to save the world she loves.
