The great alone by Kristin Hannah.
This is a story about a family trying to cope with post-traumatic stress disorder. Ernt is a Vietnam veteran who suffers from PTSD resulting in violent outbursts, Cora the wife who loves him and Leni the daughter dealing with it all. They move constantly and end up in a remote part of Alaska living off the land and becoming part of the community. Kristian Hannah in her usual manner makes the characters so real that you live the emotions with them. It is a book you don’t want to put down and be warned it will pull at your heart.
