M?o and B?

Vietnam, 1964. B? hasn't spoken a word since her mother left two years ago. Her father is now frail after a stroke, and can do little to protect her from her stepmother, Big Mother, who treats B? like an animal and a servant. After Big Mother accuses her of stealing, B? is drugged and sold. She awakes as a captive in a locked underground bunker with a group of young women. [Her cat] M?o was hiding in her shirt when she was taken. When the imprisoned women and girls manage to escape, B? and M?o must find a safe place--even thought the world is literally exploding all around them--Adapted from back cover.
