Robin McKinley's mesmerizing history of Damar is the stuff that legends are made of. The Hero and the Crown is a dazzling "prequel" to The Blue Sword. Aerin is the only child of the king of Damar, and should be his rightful heir. But she is also the daughter of a witchwoman of the North, who died when she was born, and the Damarians cannot trust her. But Aerin's destiny is greater than her father's people know, for it leads her to battle with Maur, the Black Dragon, and into the wilder Damarian Hills, where she meets the wizard Luthe. It is he who at last tells her the truth about her mother, and he also gives over to her hand the Blue Sword, Gonturan. But such gifts as these bear a great price, a price Aerin only begins to realize when she faces the evil mage, Agsded, who has seized the Hero's Crown, greatest treasure and secret strength of Damar.
Aerin, with the guidance of the wizard Luthe and the help of the blue sword, wins the birthright due her as the daughter of the Damarian king and a witchwoman of the mysterious, demon-haunted North.
