Definitely. It' broken into a series of chapters which are delusional episodes in the protagonist's mind. Also, his memories of his deceased sister play prominently in the story, so… The theme of dead and dying children is a re-occuring one. It sounds ghoulish, and it is at times, but it's not all for shock and can be pretty sad when for example he's in his childhood home and the ghosts of the family are stuck re-enacting parts of their lives.

The horror is bizarre too, it almost has a planescape off-the-wall feel at times.
