Through strange events, a little burgher maid becomes mistress of a castle of robber barons. This lonely castle of Adlerstein perched high on the rocks above a dangerous ford, is known as the eagle's eyrie. Here the twin barons are born and grow to manhood. The story tells of their love for each other, and of the separation of the brothers after the battle at the ford. How the feud between the rival barons is healed and a chapel of peace is built at the terrible ford, concludes one of the best known tales of Charlotte Yonge. Expressive illustrations by noted illustrator Marguerite de Angeli accompany the text.
