I've been playing the quite remarkable game "Murdered: Soul Suspect" and came across these books in the apartment where Ronan (the main character) has his last fight. You have to get very close to be able to see them. They have rather strange titles.
On another note, I like the room you find these in. The girl that hid in there was kinda spiritual and it shows, by the crazy drawings on the floor, the dream catcher hanging from the ceiling, and paraphernalia she adorns her clothing with!
And what the heck is that stuck to the side of the fridge, a strange picture of (what I guess is) a face with a green eye. Weird.
