The Great Alone by Kristin Hannah
Thirteen-year-old Lenora (Leni) Allbright has never really had a place she can call home. Her father, Ernt Allbright, a Vietnam POW, is always convinced that the next place they move to will return him to the man he was before the war changed him. After losing yet another job, he makes an impulsive decision to move his family to Alaska, despite Leni and her mother's reluctance to leave behind everything they know to venture into America's last true frontier.
