Karthini is born in a village where both boys and girls are born who have the gift of magic. But only the boys’ magic is trained: girls with the gift are killed through being tied hand-and-foot and put to sea in a barrel. When, at the onset of her period, Karthini suffers this fate, she is rescued at sea by a crew of woman sailors on a ship called ‘The Pearl’, and taken to an island where her magic will be recognised and trained.
