Meet Nick Sax: a corrupt, intoxicated ex-cop turned hitman, adrift in a stinking twilight world of casual murder, soulless sex, eczema, and betrayal.

With a hit gone wrong, a bullet in his side, the cops and the mob on his tail, and a monstrous child killer in a Santa suit on the loose, Nick and his world will be changed forever this Christmas by a tiny blue horse called Happy....

This deluxe edition of HAPPY includes 10 extra pages of story by creators GRANT MORRISON and DARICK ROBERTSON.
