I cannot recall any animal book which I would recommend to as wide an audience as [Born Free: A Lioness of Two Worlds, an] unusual and exciting story of a lioness raised among people and then retrained to return to her own kind in the wilds of Kenya…. It has drama and sadness, but above all novelty and happiness. Aside from its pleasurable reading it has much to offer to the animal behaviorist also—much that is thought-provoking and significant. (pp. 2445-46)
