The Proving, by Beverly Lewis
I've read very few of Beverly Lewis' books, but, after this book I think that will change. Each time I picked this book up, I didn't want to put it down. I'd read much longer than I'd planned. I was immersed in the characters and the story.
Mrs. Lewis kept you in suspense about what would happen, till the very end. Details aren't revealed quickly, but, slowly, and in the proper places. Life is like that. We need time to learn the truth and time to deal with it.
I don't want to give any plot lines out, since it would reveal too much, and spoil the book for you. I do suggest that you get a hold of a copy, and read it.
