Annemarie 'Shug' Wilcox has been friends with Mark for as long as she can remember. Now, for no particular reason, she's fallen in love with him - and every moment they spend together (but not 'together') is torture. Shug knows that there's nothing special about her. She's freckled and gawky, with a ridiculously flat chest. Is it any wonder that Mark spends all his time gaping at her curvaceous older sister?
