Greg DeMario writes stories that live in the space between heartbeats—where time bends, reality fractures, and consciousness becomes infinite. Greg DeMario is the author of 3:17: What Happens When Your Heart Stops?, a haunting debut novel that explores the mysteries of time, consciousness, memory, guilt, and the fragile line between life and death. Inspired by a personal experience that defied explanation, DeMario began writing fiction that asks profound questions about the unknown. What happens when the body fails, but awareness continues? Can time fracture under the weight of grief? Do the choices we make in life follow us beyond death? These questions form the emotional and philosophical foundation of 3:17, a speculative suspense novel that blends psychological mystery, supernatural intrigue, and deeply human storytelling. DeMario’s writing lives in the space between heartbeats, where reality bends, secrets surface, and the impossible begins to feel terrifyingly real. His fiction is designed for readers who enjoy stories that entertain while also making them question what they believe about consciousness, memory, and existence. When he is not writing, Greg can often be found with a good book, a great cup of coffee, or exploring new places. He lives on the East Coast in Maryland.
