The Journey of Elizabeth Ann Rose (Seasons of Love and War Saga #3)
Brenda Ashworth Barry

She and her family live out of an old beat up station wagon traveling from one city to another. Sometimes, living in dirty old hotel rooms where mice and cockroaches are their only pets.
When Beth Ann turns eleven she finds more than chocolate cake being served. Her mom serves her daddy divorce papers, takes her three children and heads out to begin a new life. In one short summer, Beth Ann’s life completely changes, and she ends up in Novata, a small Northern California town. The very town that will change her life forever.
