The Big House by Robert Vasvary

Everything is pitch black. The tunnel walls feel soft and slimy. A chill runs down his spine, rising panic stuck in his throat. The walls are breathing. Plunged into a world where the boundaries between fantasy and reality have disappeared, Andy’s thirst for adventure leads him to precious treasure, true love and unspeakable horror. In a bid to escape the terrifying realm of the undead and find the truth, there is only one way out: an epic showdown between good and evil that challenges everything he knows about himself and the world.
