The Secret Files of Lisa Weiss

Lisa Weiss, 12 years old, has known that she wants to be a social worker ever since she was old enough to talk, so it only makes sense that she should spend her time reading social work textbooks instead of doing her math homework. Unfortunately, her parents don't see things this way. Determined to prove that she is serious, Lisa proceeds to do casework studies on eight of the people in her life, including her best friend, a strict teacher and her younger siblings. Her project gets her into a lot of trouble -- but also changes the way she looks at people. Very humorously written.
