As Chief Tactician for the airship DeGrasse, Jacob Scarberry has spent the last six months on a wearying tour of duty. He’s missing home, and his prosthetic leg is conducting the December cold straight to his core. But with the holidays coming up, he's looking forward to a well-earned leave, sharing some Christmas surprises with his lover, Dr. H. Alphus Troyer, and welcoming in the dawn of the 20th century.

A professor at Ohio University, Al is already on Christmas break, and his unconventional household is in a festive frenzy. Al is a bit less joyous, his anticipation of Jacob's return warring with uncertainty over the special gift he had commissioned for him. Would Jacob appreciate it, or will it put a strain on their relationship?

Suddenly Al's worries become trivial when the newspapers report an attack on the DeGrasse. With Jacob fighting for his life miles away, Al is left to wonder whether Jacob will return at all, or whether the planned festivities will become holiday heartbreak instead.
