"In November 1928, one year after Lindbergh crossed the Atlantic, a pair of young newlyweds set out to run the rapids of the Grand Canyon in a homemade boat. Swept up by America's obsession with feats of daring, Glen and Bessie Hyde hoped to set a record - she would be the first woman to run that treacherous stretch of the Colorado River. A month later they vanished without a trace."--BOOK JACKET.
