story about a young girl growing up in her grandfathers cult like community

It's a story about a young girl growing up in her grandfathers cult like community. She has a baby at the end and everyone thinks its a baby from god because his hand are fused together like in prayer.. I believe the title has something Like Cain in it. The author also wrote a book about a girl living in a church...Bittersweet or Bitter root.

Rapture of Canaan, Sheri Reynolds (1995)
