4 stars. This childhood favorite of mine holds up well, capturing a palpable sense of excitement and danger, as well as the incredible locale of the Grand Canyon. Marguerite Henry anthropomorphizes Brighty well, making him a believable and lovable animal character. The cameo appearances by Teddy Roosevelt tied the story well to history. Human characters still feel human–strong, weak, good, rotten. One aspect that I found interesting is that reading this book as an adult is that Brighty’s world feels richer to me thanks to three weeklong backpacking trips I’ve spent below the rim of the Canyon. I was very glad that I reread this book.
