Cindy, a savvy yet cynical teenager, still traumatized by her mother's recent death, is appalled when her father falls in love with one of her teachers, a woman with two teenage daughters of her own. She cannot imagine a worse fate than having her teacher as her stepmother, and as for the two prissy girls, she is never going to call them sisters . . . no way! But if Cindy dislikes her prospective sisters, Ashling and Orla think she is an absolute horror -- spoiled, arrogant, and atrociously rude to them and their mother when they visit her house. Will the girls ever get along and learn to be a family? Featuring the girls' stories in two unique, back-to-back diaries, one for Cindy and the other for Ashling and Orla, readers can choose which story to begin with and will enjoy the varying viewpoints recording the same events.
