Donnie Finnerman never knew that he was different, that he was important. He certainly never expected to hear an angel talking to him, let alone the arch angel Raphael. He never even expected to think about angels after he was finally done with Sunday school.
He was just this simple mechanic from Maine. Raphael told him that it was genetic, that he was his one true vessel coming from a long like of possible vessels.
It was such an honor, to be the corporal form of an arch angel, the healer himself. It didn't take Donnie long to say Yes.
