When the annual Games go horribly wrong, the King dispatches an army to bring the rogue wizard responsible to justice. There's only one problem, this is exactly what the wizard planned. When a gifted but dangerous young mage delivers a precious prophecy to the King, foretelling the horrible fate that will befall his army, the King ignores the warning. Thus, an unlikely group forms: the mage seeking atonement, a dock rat orphan skilled with a bow, a former priestess forsaken by her order and forced to fight as a gladiator, and the son of the king's bodyguard. They must race to the Broken Tower and set things right before the King's troops fall into the wizard's trap by sailing into the Bay of Chains.
