Novelist Umberto Eco's latest book "The Island of the Day Before" tells the strange tale of a 17th century Italian adventurer who is marooned on a ship straddling the international dateline. As with his other novels, "The Name of the Rose" and "Foucault Pendulum" Eco entwines an intricate story with musings on history philosophy and what he calls "lunatic science." Eco is in the Twin Cities to read from his book. Tomorrow he travels to the St John's University in Collegeville to speak, and to visit the monastic library. He told Minnesota Public Radio's Euan Kerr he researched "The Island of the Day Before" for five years and even went to remote Pacific islands to experience life on the international dateline.
