A king returns from war to find his kingdom murdered, one plague at a time.
Who drives the story
The youngest prince, three years a prisoner of war in Brisa, who comes home gaunt and scarred to a crown he never wanted. Haunted by surviving when his golden brother Jehan didn't, he hunts his family's killers and grows from spare heir into a decisive king.
The historian's daughter, low-born and overlooked at court, who reads death records the way others read faces. She uncovers the plague's manufactured origin, becomes Cas's partner in the investigation, and ends the book appointed royal historian in her ailing father's place.
Cas's older brother, the golden heir who died during the plague years—officially from a fall from his horse. In truth he had discovered the Brisan plot and was murdered to silence him, and his tomb is where Cas's guilt lives.
The young boy Cas rescued and brought home from Brisa, a stray piece of loyalty in a stranger's kingdom. A fever scare nearly breaks Cas; the boy recovers and stands beside him on the ramparts at the end.
Cas's cold, distant mother, who greets her ragged surviving son with criticism. Beneath the frost she has known for years that Jehan was murdered and been too afraid to say so—until Cas forces the truth out of her.
Captain of the guard and Cas's last trusted ally from before the war. He guards Cas, suspects Jehan's staged fall, investigates—and is found dead in the stables, his death staged as an accident.
A noblewoman with a too-keen interest in the new king, secretly meeting a Brisan envoy. Her part of the plot was to marry Cas and control the throne; arrested, she sneers that Cas is a 'reaper' who brings death wherever he goes.
A minor noble thought to have died in the plague, in truth the masked assassin. Paid by the Brisan king to release the Red Fever in the castle and later to kill Jehan, he is unmasked in the throne room trap and executed.
Also in the story
The elderly, frail royal historian and keeper of the death records, whose ledger of the dead gives Cas and Lena their first pattern. His ailing health leads to Lena taking up his office.
A healer imprisoned alongside Cas in the Brisan camp, who whispered to him about a weaponized illness being developed by the Brisan king. She died before revealing more, but her warning becomes the thread that unravels everything.
