Her first book Murder on the Iditarod Trail (1991), was well reviewed and won both the Macavity Awards and Anthony Awards for best first novel, prompting the author to develop a series based on this book's characters, Alaskan state trooper Alex Jensen and Jessie Arnold, a sled dog racer. In 2005 she started a new mystery series featuring a 63-year-old widow, Maxine McNab, travelling in her Winnebago with a miniature dachshund, Stretch. Maxine had appeared in Dead North (2001) in the first series. Henry went on the road to research the book.
All maps for her books starting with Dead North (2001) were made by her son, Eric Henry.
