[T]he Lewins recount a trip they took in 1997 to visit Uganda's Bwindi Impenetrable National Park to "meet the mountain gorilla." Briefly captioned, thumbnail watercolors picture the jungle trek, and magnificent double-page spreads replicate the exotic surroundings and show the animals close up. A good deal of the text . . . concerns the arduous but exhilarating journey to the sites, but there is also information on the gorillas themselves. The personal voice and picture-book approach will definitely win an audience.
