One word: Terrifying.
Kyra is a 13-year-old girl living on a Religious Compound, who is Chosen to marry her uncle, a man over 50 years older than her. She immediately knows this is wrong, mainly from the books she has borrowed without the Prophet's consent. She has seen the fierce discipline around her, the mysterious deaths, the unnecessary losses and knows there is a life that is better than this for her. What she goes through and what she endures in pursuit of that other life is disturbing and heart-breaking.
The Chosen one plays out like a gory car crash that is so terrible to see and yet you can't for the life of you look away. An important book, much in the same vein as Living Dead Girl by Elizabeth Scott. These are the topics writers have to write about and readers have to read about to keep our children safe.
