This epic novel about Alaska is a beautifully constructed story about an abusive husband with PTSD, his wife and daughter moving to the Great Alone to make an unpolluted start. Descriptive detailed research makes the reading a rich experience.  There are times that the romantic elements overtake the story arc. Luckily these episodes are infrequent.  There are enough surprise turns that you can forgive any predictable outcomes. Cathartic tears will finish you off at the end.
