Aean and Sara are bound 3 times in the prophecy of the Darkening, the embodiment of evil. Each bonding carries with it a requirement that must be filled but until they can fulfill those requirements Aean is slowly being driven insane causing his magic to get further and further out of control. Complicating matters is a rogue duke who has overthrown Sara's father, King Shaddig. The pair must reclaim the throne and find a way to stop the designs of the Darkening and something far more difficult still but can they do the seemingly impossible before they themselves end up destroying the world of Mer.
