PCL (Pure Condensed Light) = FTL (Faster Than Light travel)

A butterfly's wing, a silicon chip, and a new equation for light hold the key to humankind's boldest dream--faster than light travel.

A distinguished astronomer and a sensitive young woman are hurled into a dazzling cross-galactic adventure when an unexpected discovery links the explosive uncertainties of quantum physics with the still-untapped psychic powers of the human mind.

PCL is a bold theoretical synthesis, launching a voyage through awesome wonders--and into unimaginable terrors. For Dr. Miles Prancer, at the end of his career, has made a discovery too horrifying to share with humanity. He has found a black hole in the center of the Sun, a spreading cancer that gives our solar system less than three years to live!
