She freed the last dragon from three hundred years of chains. She did not expect the dragon to decide she was his. Solvaine Tal has spent nine years making herself invisible — translating the empire's stolen secrets in a vault no one watches closely, keeping her forbidden bloodline quiet, surviving by being useful and nothing more. She is exceptionally good at surviving. She is considerably less good at the thing she does on an otherwise ordinary cataloguing evening: reading a three-hundred-year-old release incantation aloud and shattering the chains of the most dangerous creature alive. Now Vraethan — Lord of Obsidian Fire, last of the ancient dragon lords, six centuries of power and three centuries of fury finally given form — is free. And the ancient magic of a dead civilization has done precisely what it was built to do. It has bonded them. Soul to anchor. Fire to seal. She is the only thing keeping his power from burning the empire to glass. He is the only thing standing between her and every soldier the empire will send to reclaim what it considers its property. To dissolve the bond permanently — to truly free him and survive — they must cross three weeks of impassable volcanic wasteland to the ruins of his destroyed civilization, while the empire's most dangerous engineer hunts them with a weapon built from the original chains. She has a map she copied in secret. He has three centuries of patience. Neither of them was prepared for the other. A slow-burn, enemies-to-lovers dragon shifter romantasy with forced proximity, a possessive ancient MMC, hidden power, and a love story built in the ruins of everything the world tried to erase. Standalone. Complete HEA. Perfect for readers of Fourth Wing and A Court of Thorns and Roses. The fire is his. The choice is hers. Read Wings of Obsidian Flame today.
