Sarah Vowell tells the history of the fiftieth state—Hawaii. Her latest book, Unfamiliar Fishes, gives an account of the transformation of the islands by New England missionaries who arrived in 1820, an incestuous princess pulled between her new god and her brother-husband, and also looks at sugar barons, lepers, con men, Theodore Roosevelt, and the last Hawaiian queen: a songwriter whose sentimental ode "Aloha 'Oe" serenaded Barack Obama, the first president from Hawaii, during his inaugural parade.
