Collecting award-winning novelist Denise Mina's (Garnethill, Deception, Field of Blood) take on the hard-drinking master of bad-luck magic from HELLBLAZER #216-222. When an ordinary man innocently uses an incantation, he turns to Constantine for help. But when an infamous Scottish occultist gets involved, Constantine discovers he has been cursed with empathy for his fellow man and realizes that the nightmare has just begun.

As Praexis demons gather around Glasgow, feasting on the emotions, a deadly infection of empathy turns the city into a ghost town, and unless Constantine can come up with a solution, the world will succumb to the empathy plague.
