Stacey and Mary Anne are mother's helpers for the Pike family for two weeks at the New Jersey shore. Things are great in Sea City - there's a gorgeous old house, a boardwalk, plenty of sun and sand . . . and the cutest boy Stacey has ever seen.
Mary Anne knows that Scott the lifeguard is way too old for Stacey, but Stacey's in love. She fixes Scott's lunch, fetches his sodas, and spends all her time with him . . . instead of with the Pike kids.
Suddenly, Mary Anne's doing the work of two baby-sitters and she doesn't like it one bit. But how can she tell Stacey that Scott just isn't interested - without breaking Stacey's heart?
