The Chosen One
This chilling and all-too-real story takes place inside a fundamentalist polygamist cult in the Utah desert. Thirteen-year-old Kyra loves her extended family and tries not to question the elders' tightening grip on their lives, but when they command her to marry her 60-year-old uncle, she plans a desperate escape that could put her life at risk. Billed as a young adult novel, this book may be too disturbing for some readers in that age group.
