Calling All Book Enthusiasts

For all those of you who read and enjoy it, I am asking for some suggestions. I am looking for a great light read. You know the kind of book that you read and feel happy after; The kind of book that makes you smile; The kind of book that doesn't take a lot of brain power to understand; The kind of book that just makes you feel good!!! The last few I've read have been historical, heavy subjects. I realized that I don't often choose the "feel good" books or the romantic comedies. I alwasy gravitate towards serious and often depressing subjects. I'm looking for something refreshing and light. Any suggestions???
