APE HOUSE

Ape House by Sara Gruen -  This is an interesting modern day story about Bonobo Apes and the people who research them.  Which sounds very boring, but which in fact is so good that one flies through the book.  The apes have been taught sign language, and communicate with each other and humans by signing.  They are smart and the story is smart with characters who care, and a background about these incredibility intelligent animals.
