The universe’s most dangerous secret is hidden in plain sightHenry Mackay and his dog, Addy, regularly walk alongside an ancient convent wall. Today, as he passes the door, he glances at its peeling paint. Moments later he stops dead in his tracks. He returns to the spot, and all he sees is an ivy-covered wall. The door has vanished. Had it ever been there? He begins to doubt his sanity. An ill-advised curiosity results in him unwittingly embarking on an exciting trail of events with twists, turns, quantum entanglement and temporal anomalies. It becomes an unbelievable adventure to save humanity which you’ll be unable to put down. The Door is an intriguing and unique science fiction mystery from the pen of Tony Harmsworth, the First Contact specialist who writes in the style of many of the old masters.
