Marianne has passed the ultimate test required to be a Mage. She is finally powerful enough to reunite the Twelve Isles. But having exposed herself to the darker side of magic, Marianne is struggling. The magic within her is nearly impossible to control, and she becomes cruel and violent, mercilessly pursuing those who have harmed her in the past, ignoring the pleas of those closest to her to remember what's really important: saving the islands. Everything she's fought for has come down to this. Will Marianne be able to fulfill her promise to bring peace to the islands when she can't even bring peace to herself?
