Iceman's Children — James Wilson

An angel takes on Reg â€" a bitter, suicidal homeless man â€" to train him for a secret and supernatural mission requiring great faith. Reg receives forgiveness and a gift from Maria, the sister he's hurt greatly, launching him on a venture undersea and in Outer Space. He discovers a planet-killer asteroid and only he can protect the Earth. But he has many obstacles in this mission, some very close.
