FROM LAURA MONTGOMERY: Sleeping Duty: Waking Late.
Gilead Tan and Andrea Fielding survived their stint in the military, got married, signed up to emigrate to a terraformed colony world, and went into cold sleep for the journey from Earth. While they slept, the starship went through the wrong fold in space and settled for a different world, a wild world.
Three centuries after the founding of a colony on the uncharted planet, Gilead awakens to find humanity slipped back to medieval tech and a feudal structure.
Worse, the king who wants Gilead awake won’t let Gilead awaken his wife.
