Dazzled by a Dragon by Isadora Montrose

Possessive dragon blackmails curvy crystal worker.
Marriage is his price to keep her secrets.
Crystal tuner Kim thought her biggest problem was being the talentless one in a clan of powerful geo-talents. Turns out her biggest problem is a towering dragon shifter who won’t take no for an answer.
BBW Kim is equally attracted to this dominant alpha male.
But what kind of ninny marries a dude who demands marriage in exchange for keeping her clan’s deepest secret?
Billionaire Ian knows this delectable BBW is his fated mate.
In fact he claims her before he even knows her name.
However in Mystic Bay as far as paranormal talents go crystal-working is bottom of the barrel.
Protective Ian has to battle not just the town’s prejudices, but his own. And nothing gets simpler when he puts a flawed ring on her hand.
Pretty soon they’ve stirred up trouble with their Mystic Bay neighbors, and are fighting their own love battles.
This mismatched pair could use a little help from matchmakers Sully and Robin. But the sorcerer and the fairy are finally honeymooning.
