Size 12 Is Not Fat : Heather Wells rocks! Or, at least, she did. That was before she left the pop-idol life behind after she gained a dress size or two - and lost a boyfriend, a recording contract, and her life savings (when Mom took the money and ran off to Argentina). Now that the glamour and glory days of endless mall appearances are in the past, Heather's perfectly happy with her new size 12 shape (the average for the American woman!) and her new job as an assistant dorm director at one of New York's top colleges. That is, until the dead body of a female student from Heather's residence hall is discovered at the bottom of an elevator shaft.
