Soulminder
(Book)

"For Dr. Adrian Sommers, a split second of driving while distracted leads to tragedy--and obsession. His family destroyed, he devotes his entire being to developing Soulminder, a technology that might have saved his son as he wavered on the edge of death. Sommers's vision is to capture a dying person's life essence and hold it safely in stasis while physicians heal the body from injury or disease. Years of experimentation finally end in success--but those who recognize Soulminder's possibilities almost immediately corrupt its original concept to pursue dangerous new frontiers: body-swapping, obstruction of justice, extortion, and perhaps even immortality"--Publisher's description.
