The Secret Voice volume 1

The first chapter in a grand fantasy epic filled with psychic warrior monks, magic battles, monsters, and romance from the mind of Zack Soto!
Doctor Galapagos, famed warrior-monk and agent of the ineffable Red College, is on a desperate mission to unite the realms of magic and man in a last-ditch effort to stop the seemingly invincible forces of the Smog Emperor. But the good Doctor carries a secret: He is one of the few to have faced the dreaded Grey Creep and survived–but at a terrible cost. An unseen and unknown psychic menace eats away at his very soul and threatens to jeopardize his mission… and the world itself.
