Sis is a creator of brilliant children's books, including Tibet: Through The Red Box. This guy won a MacArthur Fellowship—the so-called "Genius Grants"—and it's pretty clear why. He combines media in amazing ways, and takes very complex subjects and crafts brief, clear narratives from them without losing that complexity.
Amazon has a nice blurb on Tibet: Through The Red Box:
As a child in 1950s Czechoslovakia, Caldecott Honor-winning artist Peter Sís would listen to mysterious tales of Tibet, "the roof of the world." The narrator, oddly enough, was his father--a documentary filmmaker who had been separated from his crew, caught in a blizzard, and (according to him, anyway) nursed back to health by gentle Yetis. Young Sís learned of a beautiful land of miracles and monks beset by a hostile China; of the 14th Dalai Lama, a "Boy-God-King"; and of "a magic palace with a thousand rooms--a room for every emotion and heart's desire." Hearing these accounts--some extravagant but all moving--helped the boy recover from an accident. The stories also allowed Sís's father to relate an odyssey other adults didn't seem to want to know about in cold war Czechoslovakia. "He told me, over and over again, his magical stories of Tibet, for that is where he had been. And I believed everything he said," Sís recalls. Still, after some time he too seemed to become immune, and the stories "faded to a hazy dream." With Tibet: Through the Red Box Sís finally pays tribute to this fantastical experience, illustrating key pages from his father's diary with complex, color-rich images of mazes, mountains, and mandalas. He also produces pictures of his family at home--simple, monochromatic images that are just as haunting as their Himalayan counterparts. In one, a wistful mother and two children gather around a Christmas tree, the absent father appearing as a featureless silhouette. Tibet is a treasure for the eyes and heart. Some will ask: Is it for children or adults? Others will wonder: Is it a work of art or a storybook? One of the many things that this book makes us realize is that such classifications are entirely (and happily) unnecessary.
