The Sagan Law (Paperback) (ISBN-13: 9781836717058)

When a long-dormant mystery resurfaces, one that astoundingly could involve a parallel Earth, Dr. David Colburn is forced to confront a truth that challenges the very laws of time and causality. What begins as a scientific and impossible anomaly unfolds into a sweeping story of love, sacrifice, and legacy, stretching across generations and star systems.

As humanity stands on the brink of a new interstellar era, personal choices prove just as powerful as technological breakthroughs. This is a science-fiction tale where hard physics meets the human heart-and where the echoes of one decision can shape the fate of worlds.
