"Grace Alone" by Ruth E. Meyer

Do you like books about damaged people?  Characters who don't have it all together, don't have super lives, don't know how to get through tomorrow... or even today?  If so, you're going to love this book.

Grace is a divorced mother of 4 with some hefty emotional baggage.  She's never seen any point in church or religion.  But then this guy shows up at her kids' lemonade stand, and he's exactly the sort of good, decent, trustworthy man she thought didn't exist anymore.
