Kaamil is a Two-Hearts, the fabrication of a scientist that transfers the heart of a dead mage into the body of a child to create an entirely new person. He was made to fight for the scientist, a man simply known as the Creator, in his war against the ruling powers. But he is also an Alistar, an individual selected by the gods to fix a problem mankind cannot fix on its own.
After only a few years spent fighting in the Creator's service, Kaamil is left for dead in the middle of a huge battle. A stranger finds him and hides him in the wreckage of a fallen plane to await the battle's conclusion. The stranger does not stay, but a man who is more attached to Kaamil than believably possible helps him to a sanctuary.
He spends years there learning of two very different worlds, his magic, and everything that he is; a Two-Hearts and an Alistar. Until, one day, his past catches up with him and a group of soldiers from the Creator's army find their way into the sanctuary. They are just the beginning, however. The time has come for him to begin his duties as Alistar of the Aoine Eingnei.
