SO WHAT DO YOU DO?

Two sixth graders find their third-grade teacher living in a cardboard box in the park and give him a fresh start in this contrived, misguided tale from Evans (The Classroom at the End of the Hall, 1995). Charlie isn't sure why he follows the filthy, shambling street person into the public library—until he realizes with a shock that it's Joe Adams, his all-time favorite teacher. When Charlie rushes up to talk, he is coldly rebuffed. Enlisting the help of classmate Colleen, another Adams fan, he begins bringing food and clean clothing to the box where Adams keeps his books and opera tapes, lying about his whereabouts to conveniently oblivious parents. As weeks pass, Adams slowly becomes less hostile, and at last explains how the combination of chemotherapy, divorce, and a publicized incident in which he shoved a bullying student destroyed his self-esteem, led him to resign, and eventually drove him to drink. Ultimately, Charlie and Colleen sneak him into his old school classroom for a week (it's spring break), while appreciative former students gather to get him back on his feet with a check, an apartment, and a pep rally. Evans pays warm tribute to the profound effects a teacher can have, and suggests that helping the homeless often requires more than finding them places to live. Still, there are several characters and subplots undeveloped, and in Charlie's example is a potentially dangerous course of action. (Fiction. 10-12)
