The One and Only Ivan (The One and Only Ivan, #1)

by Katherine Applegate

You can only throw so many me-balls at humans before you get bored.

For some reason, my visitors never seem to carry any.

Bob used to have three brothers and two sisters. Humans tossed them out of a truck onto the freeway when they were a few weeks old. Bob rolled into a ditch.

Then they chopped off their hands, their feet, their heads.
