This slim novel covers the span of a summer holiday. Cecile is 17, fresh from a life in convent schools, living in a summer villa with her hedonistic, raconteur father and his young mistress Elsa. Cecile is content with their life--her father doesn't expect her to study for university exams, and she and he swap stories of their conquests and adventures. Then Anne, a long time friend of Cecile's dead mother, breezes into their lives. Cold, polished, self-possessed, Anne changes every aspect of their life and very quickly Cecile begins to resent Anne's presence. She spends the summer scheming of ways to get Anne out of her life with vaguely predictable consequences. What is fun about this novel is that it is very vivacious and racy for something published in 1955 by an 18-year old; unfortunately, it is a bit trite and the plot development is clunky. The reader can guess every twist but despite the predictability, it is a fast, beach-y fun read.
