It's 1944, and ten-year-old Janet Baylor is leaving India with her family to return to the United States after living abroad for seven years. Onboard a troopship, dubbed the U.S.S. You-Know-Who, their perilous journey is filled with excitement and mystery. Because the ship is passing through enemy waters, it must travel incognito and zigzag to avoid torpedoes. As Janet and her brothers explore the ship, the ever curious Janet finds there are secrets to be discovered; she wants to know why the beautiful Ann Dobson is fleeing India and why the Eurasian boy Lee is so mysterious about his past. And when the Baylors finally arrive in America, Janet is amazed by the strangeness of it all as she gets ready to begin her new life.
