Search - Forever in Blue - The Fourth Summer of the Sisterhood

This is the 4th book in the Sisterhood of the Traveling Pants series. In this book, the girls learn to come to terms with love and what their friendship is really made of as they realize that they are now adults. Although Tibby's story is usually the most interesting to me, this time I think Lena's story was the most outstanding as her character really develops into her own person (something we caught a glimpse at in the 3rd book).
