The Serpent King is the most eligible bachelor in the land: a monster with dark and terrible magic and the ruler of the last free kingdom. Riches and power await his future bride — but also a life forever trapped in the games of court.

That fate is eighteen-year-old Saphira's worst nightmare. Ever since the Empire made her an orphan, she’s found freedom in being invisible. So, despite her rare gift for harnessing the magic in gemstones, she lets an unscrupulous jewelsmith take credit for her increasingly sought-after work.

But when the king sends his most clever huntsman to find the best jewelsmith of all, the spotlight lands on Saphira. Faced with choosing between falling into the Empire’s grasp or marrying a monster, she chooses the latter — even if it means getting increasingly caught between her cold, serpentine husband and his cunning, handsome huntsman.
