“From now on I’m Alan of Trebond, the younger twin. I’ll be a knight.” Alanna has always craved the adventure and daring allowed only for boys; her twin brother, Thom, yearns to learn the art of magic. So one day they decide to switch places. Disguised as a girl, Thom heads for the convent; Alanna, pretending to be a boy, is on her way to the castle of King Roald to begin her training as a page. But the road to knighthood is not an easy one.
