A miller's daughter (who can definitely be read as a POC, although it's not overt) is pursued by a nobleman with a Bluebeard-esque agenda: he already has six wives imprisoned in his manor! As the blurb says, "Lord Crevan gives Rhea a series of magical tasks to complete, with the threat 'Come back before dawn, or else I’ll marry you.'" GULP. Filled with adventure and magic, this fantasy features a truly strong female lead, and is appropriate for YA readers, although it's not specifically marketed as YA (as far as I know). No swooning over sparkly vampires here!
I highly recommend it.
