Fudge books volume 3
Sometimes life in the Hatcher household is enough to make twelve-year-old Peter think about running away. His worst problem is still his younger brother, Fudge, who hasn't changed a bit since his crazy capers in "Tales of a fourth grade nothing". If you ask Peter, Fudge is just an older, and bigger, pain. Then Peter learns that his mom is going to have a baby and the whole family is moving to Princeton for a year. It will be bad enough starting sixth...
While spending the winter of 1947-1948 in Miami Beach with her family, ten-year-old Sally makes up stories, casts herself in starring roles in movies, and encounters a sinister stranger.
