The Talisman takes place at the end of the Third Crusade, mostly in the camp of the Crusaders in Palestine. Scheming and partisan politics, as well as the illness of King Richard the Lionheart, are placing the Crusade in danger. The main characters are the Scottish knight Kenneth, a fictional version of David of Scotland, Earl of Huntingdon, who returned from the third Crusade in 1190; Richard the Lionheart; Saladin; and Edith Plantagenet, a relative of Richard.
