Ex military woman now a Park ranger finds lost dog

Buck is a big-hearted dog whose blissful domestic life is turned upside down when he is suddenly uprooted from his California home and transplanted to the exotic wilds of the Yukon during the Gold Rush of the 1890s. As the newest rookie on a mail delivery dog sled team—and later its leader—Buck experiences the adventure of a lifetime, ultimately finding his true place in the world and becoming his own master.

John Thornton, is a fearless man who's after more than gold; he wants to do what's right. Thornton works for the U.S. mail and is the only person daring and smart enough to figure out how to travel the deadly 600 miles from Skagway to Dawson, Alaska in the icy winter. His incredibly dog Buck is by his side and part of how he survives.
