Adrian Bonenberger is joined by Brian Castner and Andrea Pitzer to talk about their newest books. Castner's Stampede: Gold Fever and Disaster in The Klondike" looks at the gold rush in Alaska and Canada that unfolded at the end of the 19th century, while Pitzer's "Icebound: Shipwrecked at The Edge of The World" returns to the 16th century to examine a trade expedition that sought a shortcut to China via a legendary temperate north sea. Both journalists and writers decided to explore the land they were describing, in the process of writing their books.
