Winner of the 2004 Stonewall Society Imagination Literary Award for best gay-themed science fiction. "It is 2479 AD. Technical Sergeant Kallen Deshara and his team have traveled from the 25th century to the 19th. Their mission: to eliminate powerful ion storms caused by the very device that opened the portal to the past. If they don't succeed, their present may cease to exist! Once done, they'll return home and the future will be as it should be. But Kallen didn't plan on meeting Aaric Utzman, a young cartographer from post-colonial America. Nor did he plan to fall in love with him. He must find a way for them to stay together or Aaric will have been dead for over six hundred years after Kallen's return. No matter what he decides, the past, the present, and the future will be irrevocably altered."
