Ape quartet

Sophie is not happy to be back in the Congo for the summer, but when she rescues an abused baby bonobo she becomes more involved in her mother's sanctuary--and when fighting breaks out and the sanctuary is attacked, it is up to Sophie to rescue the apes and somehow survive in the jungle.

When John was ten years old his father brought back a baby orangutan from Indonesia, and Raja quickly becomes John's "brother" and responsibility--so years later, after his parents divorce, and his father has sold Raja to a roadside zoo, John sets out to rescue him and bring him to a sanctuary in Indonesia.
