Gingerbread (Cyd Charisse #1)
Rachel Cohn

When Cyd's rebelliousness gets out of hand, her parents ship her off to New York City to spend the summer with "Frank real-dad," her biological father. Trading in her parents for New York City grunge and getting to know her bio-dad and step-sibs is what Cyd has been waiting for her whole life. But summer in the city is not what Cyd expects -- and she's far from the daughter or sister that anyone could have imagined.
