Gr. 5-up. "Are you lost, son?""Yes . . . I mean, no. I need a job."The words are minimal in this picture book for older readers. An Asian American youth gets a job as a sign painter. He wants to be an artist and paint landscapes, but he's being paid to paint a poster girl on a dozen blank billboards scattered through the desert. Then there's a raging dust storm, and the model from the picture sweeps past in her car and doesn't come back. In a tribute to many modern artists, including Hopper, Warhol, and Magritte, Say shows and tells how their pictures make you feel and how the surreal is part of a young man's search for himself. In fact, the story expresses the wildness in ordinary life, both precise and mysterious, where the blonde on a billboard suddenly sweeps past you, and the all-night diner down the street is as desolate as you feel. Older readers who know the famous pictures will enjoy Say's homage to the masters, even as they are moved by the young man's conflict: Should he stay safe and earn his wages? Or should he follow his dreams?
