Charlie came into Helen Thayer's life when she set out to ski alone to the magnetic North Pole. Helen was a 50-year-old adventure traveler with a dangerous trek in mind; Charlie was a nameless Inuit sled dog who deserved a name and a better life. Helen gave him both. Together they traveled 364 miles to circumnavigate the entire magnetic North Pole area. Charlie's loyalty and courage never wavered as they survived the unstable, dangerous Arctic sea ice, endured the violent storms than can last for days, and defended against the polar bears who can hunt and kill humans for food. Seven times Charlie confronted hungry polar bears, each time ready to give his own life to protect his companion. Helen contributes her survival on her journey to the magnetic North Pole to Charlie.
