If the book were simply the story of the Ribkes and Looee, A BEAUTIFUL TRUTH would still be a remarkable achievement. But the narrative’s radical other half, which unfolds in loosely alternate chapters and focuses on a group of chimpanzees in a Florida research institute, invoking their perspective, lends the novel a rare depth… McAdam’s acknowledgements attest to serious secondary reading—Frans de Waal and Sue Savage-Rumbaugh are both cited—but his depiction of simian life’s limitations turns research into rhapsodic lamentation.
