A global phenomenon of a VR game called Whispers from the Abyss suddenly appears. At first, players think it’s simply the most realistic experience ever created. But as the game progresses, its monsters begin appearing in the real world. Players’ SAN values, or sanity levels, become a dimension that affects reality, while the game’s mythological creatures and Great Old Ones begin to invade and rewrite the laws of physics. Humanity goes from hunting for thrills to becoming the hunted.
