I am so glad I did!
It is a novel written by Susan Meissner, published in 2009. Meissner is Christian writer, winner of the Christian Book Award for Fiction. I love being surprised to see Christianity sprinkled in a book. Particularly when unexpected.
I'm am borrowing Elizabeth Musser's praises of the book:
"Poetic prose and a 'can't put it down' plot makes White Picket Fences a great read. It is a thought-provoking look into a dysfunctional family that thinks it's functional and how an outsider can serve as a means of grace."It's that good. Grab a copy, and enjoy.
