But saving a continent isn't as easy as a prophecy makes it sound, and 'facing a great evil' definitely requires more the fiery silk that Luna is uniquely able to create. As she fights her way to the abyss that hides the dark roots poisoning Pantala, Luna must uncover a long-buried secret and unite her friends, her enemies, and her own powers. If she doesn't, she won't get to change the world. She'll have to say goodbye to it - forever.
