This is one of Tracie Peterson's best series. She makes it exciting and draws you into the book, while also having some very good parts about God and faith. These books were the first of hers I read, and they remain my favorite.
Karen, Grace, and Karen's aunt Doris are three of the most diverse characters I've seen in a book that remain fast friends. Grace is meek and shy; Karen is anxious for women to be seen as humans and have equal rights; Doris is an old spinster with a straight-forward view of life, believing in the education of women and children.
The plot of the first book, Treasures of the North, caught my attention... and held it. I have to say I didn't expect the events in the second and third books, Ashes and Ice and Rivers of Gold. Tracie Peterson weaves words like a magician, something I strive to achieve. When I'm wanting for a book to read, the Yukon Quest is one of the first I consider.
