After trying to take Hamburger-a-gogo land, also known as the United States, by storm when her family vacations in Memphis, Tennessee, a British teen returns home to deal with the attentions of too many boys, weird parents, and mad cats.

Self-conscious about her knobby knees but confident in her acting ability, fourteen-year-old Tallulah spends the summer at a Yorkshire performing arts camp that, she is surprised to learn, is for girls only.

British teenager Georgia Nicolson's humorous diary entries reveal the results as she finally chooses between potential boyfriends, but then becomes involved in a play with the one not chosen, further complicating her love life.

Fourteen-year-old Georgia continues her diary in which she records her misadventures trying to reclaim the attention of seventeen-year-old Robbie, while coping with her friends, family, and dog-like cat Angus at the same time.
