After being transported to the Cretaceous period in Danger, Dinosaurs! Emily and Matt, the inquisitive duo, are ready for another time-traveling adventure. So with sketchbook and digital recorder in hand, they once again rub the sled’s magic logo. This time, they find themselves in the gold rush of the late 1800s. They soon catch Klondike Fever, but will they find gold or lose their shirts? The people are colorful, the land is rugged, and the adventure is unlike anything Matt and Emily have ever experienced. Dean Griffiths' black and white illustrations add detail to this daring tale. -- From Amazon.com Product Description
