The MacGregor family outwits archaeological thieves and battles ecoterrorists in the Alaskan wilderness. After surviving Caribbean hurricanes, East African ivory poachers, and Egyptian tomb raiders, the MacGregor clan is now in chillingly beautiful Alaska, battling grizzly bears, jewel thieves, and ecoterrorists. While father Jack meets with oil companies and environmentalists to assess the impact of oil drilling in the Arctic National Wildlife Refuge, his children, Chris, Ryan, and Heather, work to solve archaeological mysteries and halt plots to destroy the Alaskan wilderness. -- From Amazon.com Product Description
