sturlington: Better Joe Hill, in my opinion.

level250geek: Adapting the story of Faust in three unique ways, Carey examines humanity's relationship with sin, temptation, and evil.

sparemethecensor: Similar plotlines and styles, though the narrative in Come Closer is more personal and Horns more distant.

level250geek: Stephen King's seminal work of horror, this book also confronts evil and humanity, putting in the reader's face things they'd rather not see.

level250geek: Hill was obviously inspired by this work, which frames Satan as a tragic hero, much like the way Ig is characterized in Horns.

BookshelfMonstrosity: If you like the darkly humorous aspects of Horns, you may like You Suck. Like Horns, You Suck has paranormal elements, and the protagonist has to cope with newly found powers after a mysterious occurrence.
