When Steven Grant, a mild-mannered gift-shop employee, becomes plagued with blackouts and memories of another life, he discovers he has dissociative identity disorder and shares a body with mercenary Marc Spector. As Steven/Marc’s enemies converge upon them, they must navigate their complex identities while thrust into a deadly mystery among the powerful gods of Egypt.

Set after the fall of the Empire and before the emergence of the First Order, we follow the travails of a lone gunfighter in the outer reaches of the galaxy far from the authority of the New Republic.
