In a world where humanity lives on the brink of extinction, monstrous beings known as Daimons hunt human souls without understanding mercy, morality, or remorse.

Aiden is humanity’s most feared weapon-he possesses a rare and dangerous ability—Empath—which allows him to connect with the hearts, minds, and souls of spiritual beings.

By touching a Daimon, Aiden can steal fragments of its soul and gain the knowledge needed to destroy it.

But every soul he absorbs leaves something behind.....

As the war against the Daimons escalates and the terrifying I-King, ruler of the Daimon legion, begins his march to annihilate humanity, Aiden is forced to push his power further than ever before.

The line between man and monster begins to fade.

To save humanity, Aiden may have to sacrifice the one thing he has left—
his own humanity.
