In Norris Bloom's third book of the Crowns and Kingdoms series, Sundiata receives a letter from his best friend, Queen Zora. He knows at once that he must leave the cottage in Tarshish and travel to the far away kingdom of Nok on the dark continent. Sundiata finds the medieval kingdom of Nok vastly different from that of Tarshish, particularly for the people of Nok, who live in constant fear of a ghost ship that takes people in the night. As Sundiata unravels the mystery of the ghost ship, he befriends Princess Tahtahme and helps solve the mystery of her missing twin brother.
