This, the second of the two Sisterhood of the Travelling Pants films is taken from the last three (of four) books by Ann Brashares takes place during the summer following the first film.
The girls are again being separated as they follow their summer plans. The film is very much in the vein of the first one, so if you liked that one you will like this as well. Covering three books, it does feel a little disjointed in places though and you do have to wonder if it would have worked better not to cover so much. It is still a very enjoybale film to watch and provides a fitting conclusion to the story.
