Footsteps of Angels

Empire builder Max Feyman had ruthlessly gained control of an invention called the 'zipdrive', a system of ultra-fast space travel. But his world is shattered when his daughter Celia, vacationing on the moon, is suddenly rendered unable to walk or speak - dependent on others to remain alive. Then, across the solar system, others are also struck down. Feyman must find a cure for the mysterious affliction that threatens not only the life of his only daughter - but also humanity itself.
