I have a couple of light-hearted books loaded onto my e-reader, waiting to be read -both are books based years later... the first is Sisterhood Everlasting by Ann Brashares, a story occuring 20
years after Sisterhood of the Travelling Pants, as well as Sweet Valley Confidential, 10 years after the Sweet
Valley High story ends. Of course you would have to have read/seen the movie or read Sweet Valley High (I might be too old!) Just a couple of suggestions!
