PIER MARIA COLOMBO was born in Athens to an Italian father and a Greek mother, dividing his early years between the two nations. He studied Geological Sciences in Naples before shifting his focus to the stage, where he worked for several years as a set designer—a discipline that honed his ability to build immersive worlds. A prolific author, Colombo moves fluidly between horror, thriller, and science fiction. His bibliography includes the medieval horror fantasy saga Gioncavallo, the space opera series Space Post Express, and standalone novels such as Underneath, The Cracked House, Campfire, The Boy Who Disappeared in His Room, 101 Demons, Forklift Driver, A Greek Horror Story, FUZ, Wonderland Skate Park, Diary of a Zombie, and The Guardian Demon.
