The Hole by Oyvind Torseter

From chapters.ca:
The protagonist of The Hole has discovered a hole in his apartment and tries to find an explanation for it. He seeks expert advice. But not everything can be explained. Perhaps he'll just have to accept that the hole is there? The Hole has simple, expressive drawings created by pen and computer, and there's a hole punched right through the book, so it really exists, even if it can't be explained.
