Halli Sveinsson has grown up in the House of Svein, hearing the legends of the heroes as all his forefathers did. Theirs is a peaceful society, where the violence of the past has been outlawed and disputes are settled by the Council. But young Halli has never quite seemed to fit in with the others. For starters, he is neither handsome nor tall, like his siblings. He's stumpy and swarthy, with a quick mind and an aptitude for getting into trouble. Bored with everyday chores and sheepherding, he can't help playing practical jokes on everyone, from Eyjolf, the old servant, to his brother and sister. But when he plays a trick on Ragnar of the House of Hakon, he goes too far, setting in motion a chain of events that will forever alter his destiny. Because of it, Halli will have to leave home and go on a hero's quest. Along the way, he will encounter highway robbers, terrifying monsters, and a girl who may be as fearless as he is. In the end he will discover the truth about the legends, his family, and himself. Jonathan Stroud's stunning new novel is a funny and epic saga, as well as a surprising look at the real meaning of heroism.
