Dragon Drive: A Comedia Mundana: Volume 1: The Finger of God Book 4: A Hole in Time

Diablo Keep is haunted by four billion years of Life's dreams and prayers and tragedies, banshees bewailing all the dying world's ending. Yet hope is still possible, for a new spirit informs the leaders of this greatest of keeps, and comes with a message for all the Earth. Paul Royer, his despair transformed into wonder and joy, comes back from his strange encounter on the cliffs above Diablo Keep with gifts for all the ages to come and a bridge to eternity for the children of the dying Earth.
