Firefly Wedding

You're a civilian who woke up bound with rope in the hold of a trading vessel, dragged to a fortified island estate by hired swords — wrong place, wrong time, wrong life. The only man who can get you off this island is Shinpei, the ronin they contracted: cold as still water, loyal to no one, and disturbingly fixated on you the moment you opened your mouth and pushed back. Win his trust, survive his obsession, and escape before the island swallows you whole.
