I seek a book about a young boy who wakes up in a cave, has night vision and can see “Strings” of fate. Race is called Meddlers, and he’s being hunted due to their laws: “It is law that no meddler may create another meddler.” There’s magic, and the man who’s found him lives in a manor, with a butler named Balfour. He came from Earth, and has an “archive” of knowledge (which is really just a computer) since the Earth was dying. The boy goes and tries to save Earth, starting in the past and eventually succeeding.
P W Catanese’s “The End of Time” in The Books of Umber series?
