I Ran from the Dragon King. He Hunted Me Down.

Cursed scholar Elara thinks she's helping a lonely dragon find a mate. She teaches him the courtship song, demonstrates the dance, and realizes too late that he's performing both for her. Opal isn't an ordinary dragon. He's an ancient king who claims his bride—and remembers a promise she forgot. Their blood pact may be the only cure for her curse. But when he carries her into his sealed mountain lair, can Elara recover the truth before his fear becomes her prison?
