A group of Spanish explorers, led by Captain Mendoza and his guide Zia, set out on an expedition searching for gold. His fellow explorers were: Torres, who took care of the horses, Father Francisco, who came to spread faith to the Indians, Este'ban de Sandoval, who wanted to be the first person to make maps of the uncharted land, and Roa, the drummer. As the group travels on they have many adventures with the Indians. After awhile the group joins several other Spaniards. As they travel on they get into a war and Mendoza's group leaves to find gold in the mountains. Through their adventure up in the mountains they are hit by a storm and are forced to live in a cave for a few days. At the end of the story they steal gold from the Indians which leads to some tragic consequences. You'll need to read the book to find out what happens to the explorers. I would definitely recommend this book because it was very exciting and had lots of action from start to finish.
