Sera survives the extermination of House Hallowyn after treasonous rivals frame her family for poisoning the imperial chalice. Exiled to the frigid Evernight Wall to be claimed as a border bride, Sera awakens with memories from her slaughtered past life. Knowing nocturnal horrors will soon breach the fortifications, she deliberately chooses Kael, an unranked garrison sentry shunned for his penury.
Deploying forbidden botanical magic, Sera revives barren tundra farmlands, transforming her new household into a fortified bastion. She soon uncovers Kael's buried secret: he is Kaeldros Drakon, the concealed sovereign of the dragon throne. As imperial armies march north to eliminate surviving heirs, Kael assumes majestic dragon form, joining Sera to settle historical blood debts.
