Penny has a secret. Under the alias GirlOnline, Penny blogs her hidden feelings about friendship, boys, high school drama, her quirky family, and the panic attacks that have begun to take over her life. When things go from bad to worse at school, her parents accept an opportunity to whisk the family away for Christmas at the Waldorf Astoria in New York City. There, she meets Noah, a gorgeous, guitar-strumming American. Suddenly Penny is falling in love - and capturing every moment she spends with "Brooklyn Boy" on her blog. But Noah has a secret, too, one that threatens to ruin Penny's cover - and her closest friendship - forever.
