In this collection of stories, every page hides a door that should not be opened. You will meet a stranger who smiles at you in the mirror, hear the scratching of nails on the wall, and discover that "it" that appears on time every night is actually sleeping next to you.
Warning: Do not read alone late at night. Because fear does not end when you close the book - it will hide in your shadow and accompany you to the endless darkness in front of the light switch.
