The Guest Book is the featured novel of the month at www.shereads.org, where Mary Beth is part of the lead team with Ariel Lawhon. I have read many of the novels they have suggested and I have not been disappointed. If you're looking for a good book, it is a great place to start.
As for me, I am at Sunset Beach this week and I will be popping into the Pelican Bookstore to get my copy. The rest of the day, weather willing, I will be sitting on the beach, my toes in the sand and a cold Diet Coke nearby enjoying the story of The Guest Book.
