DESCRIPTION:“‘I hate this old school,’ Martha said.
‘Oh, so do I!’ Victoria said.
‘It’s worse than it was last year,’ Martha went on. ‘Pretty soon I’m going to live home and go to day school. are you going home for Thanksgiving?’
Victoria shook her head. ‘I guess not.’
Martha and Victoria are best friends at boarding school. They share all their joys and sorrows- and a secret language, too.”(from the back cover)
