The Chosen One

Thirteen-year-old Kyra has grown up in an isolated community without questioning the fact that her father has three wives and she has twenty brothers and sisters. That is, without questioning it much - if you don't count her visits to the Ironton County Mobile Library on Wheels to read forbidden books, or her secret meetings with Joshua, the boy she hopes to choose for herself instead of having a man chosen for her.
But when the Prophet decrees that Kyra must marry her sixty-year-old uncle - who already has six wives - she must make a desperate choice in the face of violence and her own fears of losing her family forever.
