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.

A Newbery Honor Book and a modern classic of young adult fantasy, The Blue Sword introduces the desert kingdom of Damar, where magic weaves through the blood and weaves together destinies. New York Times–bestselling and award-winning author Robin McKinley sets the standard for epic fantasy and compelling, complex heroines. Fans of Sarah J. Maas, Leigh Bardugo, and Rae Carson will delight in discovering the rich world of Damar. Harry Crewe is a Homelander orphan girl, come to live in Damar from over the seas. She is drawn to the bleak landscape, so unlike the green hills of her Homeland. She wishes she might cross the sands and climb the dark mountains where no Homelander has ever set foot, where the last of the old Damarians, the Free Hillfolk, live. Corlath is the golden-eyed king of the Free Hillfolk, son of the sons of the legendary Lady Aerin. When he arrives in Harry’s town to ally with the Homelanders against a common enemy, he never expects to set Harry’s destiny in motion: She will ride into battle as a King’s Rider, bearing the Blue Sword, the great mythical treasure, which no one has wielded since Lady Aerin herself. Legends and myths, no matter how epic, no matter how magical, all begin somewhere.
