The El Dorado Adventure

Vesper has just learned that she owns a volcano in the tiny republic of El Dorado-and Vesper being Vesper, she and her guardian respond to the mysterious telegram by sailing to Central America. Almost as soon as they've arrived, Vesper and Brinnie are thrust into danger. Someone wants her property, and they will stop at nothing to get it-even if that means destroying an entire tribe of Chirica Indians and Vesper herself!
