Inquisitor Eisenhorn returns in a stunning new novel that pits him against his oldest foe, forcing him to finally confront the growing darkness within his own soul.

Inquisitor Gregor Eisenhorn has spent his life stalking the darkest and most dangerous corners of the galaxy in pursuit of heresy and Chaos, but how long can a man walk that path without succumbing to the lure of the warp?
