In one man, two souls fight for survival—and for mastery of an outlaw magic that could save a kingdom.

It was a fate Josan once considered preferable to death.

For the uneasy truce between him and Lucius is unraveling in a form of madness that is destroying the body they share. There’s only one hope for a cure.
