The Nagasaki Vector

To his bosses at the Ochskahrt Memorial Academy he was Captain Bernard M. Gruenblum, Temporal Division - just another time traveler. But to the aliens from Yamaguchi he was, literally, God. So, if Bernie was going to medieval Japan, they were too. Well, three of them. It was supposed to be a routine historical survey, but things livened up when a mutiny knocked Bernie off course. With disillusioned aliens for a crew and a brig full of murderers, Bernie knew getting home would be tough - and that was before the time machine disappeared!
