Every haunting is an unbalanced equation. For over a century, the basement laboratory held a secret that defied the rigid laws of modern science.

When a brilliant but isolated physicist risks his career to study a recurring electromagnetic anomaly known simply as the ghostlight, he unearths a century-old legacy of devotion, tragedy, and unfinished calculus. Fused into the foundation masonry during a catastrophic university laboratory fire in 1892, a brilliant consciousness remains caught in a perpetual thirty-six-minute loop—repeating its final moments of absolute sacrifice evening after evening.

To save a structure from collapsing under resonance, you don't fight the vibration. You match it.

Spanning generations of seekers—from an early female pioneer who first mapped the displacement, to an old mentor who abandons institutional logic, to the quiet junior professor who remains behind as the final witness—The Calculation of Loving Ghostlight is a gripping, intellectually profound journey into the absolute value of human purpose. It is a story where the boundaries of the present moment collapse, the scaffolding of the physical world is stripped away, and a trapped wave finally finds its permanent constant.

Perfect for fans of Interstellar, The Time Traveler's Wife, and brainy, emotionally resonant speculative fiction, this hauntingly atmospheric novel explores what happens when love becomes an immutable law of the universe.
