An execution gone wrong throws a witch and a runaway bride into the world of pirates. Seren - a girl too smart for her own good - and Eiryn - a noble girl forced into marriage - meet each other on the gallows, sentenced to hang for their crimes. But when a pirate crew accidentally saves their lives, their whole world takes an unexpected turn. The Three Seas await them, bound under the shadow of the Pirate King. Will things fall in place, like sand in an hourglass, or will they break and sink in the darkness of time?
