Dragon Guardian of Land by Keira Blackwood

Captain, treasure hunter, skeptic—Astra is a lot of things.
Or at least she used to be. Can she still call herself a captain after her ship wrecks? Is she a treasure hunter if the relic she’s been hired to find isn’t real? No matter what happens, she’s still a skeptic.

Unless magic is real.
One thing she’s definitely not—she’s not the kind of girl who’s saving her v-card.
Try telling that to the guys binding her to a rock as a “chaste” sacrifice. Sadly, no one listens to what you have to say when there’s a gag in your mouth. All Astra knows for certain is that things can’t get any worse. Until a make-believe scaled monster swoops down out of the sky. Until he turns into a ripped AF, very naked, human man who claims her as his mate.
