Rapture of Canaan (Oprah's Book Club)

At the Church of Fire and Brimstone and God Almighty Baptizing Wind, Grandpa Herman makes the rules for everyone, and everyone obeys, or else. 

Try as she might, Ninah hasn't succeeded in resisting the temptation of her prayer partner, James, and finds herself pregnant.

She fears the wrath of Grandpa Herman, the congregation, and God Himself.

But the events that follow show Ninah that Gods ways are more mysterious than even Grandpa Herman understands.
