a wonderful dilema

i have just finished reading a book, a fluffy novel telling the story of an Italian girl and her family growing up in a milltown on the East Coast in the 1920s. now i have the dilema of choosing what to read next. only a true reader understands this quandry. when you finish a good book there is a feeling of satisfaction like drinking a really good cup of coffee or enjoying a pefectly moist and dense brownie. it's wonderful, but at the same time it's over and even if you have a stack of good books in front of you, it takes a little while to get into another story, introduce yourself to a new set of characters and immerse yourself in their life's story. so here i am sitting in front of my bookshelf, weighing my options between the Grapes of Wrath, which i know will be wonderful, but it seems a little daunting, a Jodi Picoult novel, equally wonderful, but much lighter, and an assortment of other novels. what will it be? in the end there isn't a wrong choice, but there are certain moods for books, so which one is best for the end of January?
