Dana Stabenow was born and raised in Alaska. She worked in a number of distinctive Alaskan jobs, including salmon fisheries and the TransAlaska pipeline. When she turned thirty she returned to college then started writing. After a few science fiction novels she hit upon mysteries, with A Cold Day for Murder(1993) featuring Kate Shugak, the first of 15 in a continuing series. In 1998 she launched a new series with Fire and Ice, featuring Liam Campbell.
Kate Shugak is an Aleut (Native American) living in a cabin in a remote national park in south-central Alaska (resembling the Copper River area and Wrangell-St Elias National Park). Other characters include the district attorney, a state trooper, a ranger, and Kate's grandmother. In addition to the park area these novels feature Alaskan fishing grounds and the North Slope oil fields.
Liam Campbell is an Alaska state trooper who has the bad fortune to be posted to a remote area named Bristol Bay. With his bush pilot girlfriend he travels to interesting Alaskan scenes including a gold mine and an airplane crash site.
I am pleased to see that Stabenow's web site has maps of the fictional locations in her novels. In fact the maps were drawn by Cherie Northon of Mapping Solutions, with whom I taught cartography at UC Berkeley before she moved to Alaska.
