A review by seifknits
Half Brother by Kenneth Oppel

3.0

1970s story with the POV of a 13-year-old boy whose parents are engaged in a scientific project to teach a chimpanzee to use sign language.

I enjoyed the book, but thought Oppel backed off a little at the end. At one point, I thought he was going to make a point about what language really is (and isn't), but he made a 90-degree turn and his point instead seemed to be about using animals for scientific research. Should have stuck with the language issue.
