Book excerpt: A child of two worlds -- the son of an aristocratic Spanish military man turned landowner and a Shoshone warrior woman -- young Diego de la Vega cannot silently bear the brutal injustices visited upon the helpless in late-eighteenth-century California. And so a great hero is born -- skilled in athleticism and dazzling swordplay, his persona formed between the Old World and the New -- the legend known as Zorro.
