Gustave Aimard 
Queen of the Savannah [PDF ebook] 
A Story of the Mexican War

Though born in France, author Gustave Aimard spent a long stretch of his life roaming the Western territories of the United States. He was particularly fascinated by the rough-and-tumble borderlands that stretch across the vast area that is now California, Texas, New Mexico and Arizona. The thrilling action-adventure tale The Queen of the Savannah unfurls against the backdrop of a local uprising that gradually takes hold across the region.
