I liked the other Green Knowe books, but this is a complete departure. The writing is still good, but instead of revolving around the house and it's inhabitants from past and present, this story is about a gorilla escaping from the zoo and the ending is tragic. I could see it coming a mile away, but somehow I was compelled to keep reading even though I normally avoid books in which animals are killed. I'm sure that's because of the good writing, but I wish I had stopped. I wouldn't recommend this for children who are traumatized by the death of animals.
