A prolific writer of over eighty books, Catherine Woolley published so many children's books that her publisher recommended using a pen name for some of her works. Ms. Woolley's Ginnie Fellows series was and continues to be a reader favorite across generations.
A quick read with nice period detail that made me recall the reading of my youth. The story is innocent, engaging, and not overly complicated. There are a few good red herrings that keep the reader guessing. The only dated flaw is reference to "hippies".
