The Waking Late Trilogy

Contains all three books in the Waking Late trilogy.
Sleeping Duty (book one)
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.
Out of the Dell (book two)
On the planet Nwwwlf, in the lost colony of First Landing, the original settlers carved out one sylvan valley, a lone outpost where humans flourish. But their bright hopes and best intentions devolved over centuries into a rude replica of medieval feudalism.
Gilead Tan, who had been held captive for centuries in his sleeping cell, survived treachery and pain to free a small group of sleepers. But he and his friends now face the perils of life outside First Landing’s sanctuary - without their powered armor, their tools and technology, or anything else they need save for a few chickens.
Gilead must establish a safehold for his crew, but the alien environment does not welcome them, and petty bickering threatens their meager resources. He hopes that a trace of smoke - spotted above a distant ridge - beckons them to a better place.
It doesn't.
Like a Continental Soldier (book three)
The starship Valerie Hall failed to reach the terraformed world of its original destination. Instead, it found a habitable substitute where the settlers split into two factions. First Landing devolved into a rude replica of medieval despotism. Seccon might promise more.
Or so hope Gilead Tan and his companions.
Gilead spent three centuries in cold sleep, held there by a First Landing custom that decreed only one sleeper could be awakened every 50 years. Once awake, Gilead freed two dozen of his fellows - all soldiers like himself - and led them into the wilderness.
Close to 200 civilians still lie trapped in the decaying cryo-cells of First Landing. Their captive slumber haunts him.
But despite its vaunted freedom, Seccon has one rule. No one goes back to First Landing.
