From #1 New York Times bestselling author Sarah Dessen comes a big-hearted, sweeping novel about a girl who reconnects with a part of her family she hasn't seen since she was a little girl--and falls in love, all over the course of a magical summer. Emma Saylor doesn't remember a lot about her mother, who died when Emma was twelve. But she does remember the stories her mom told her about the big lake that went on forever, with cold, clear water and mossy trees at the edges. Now it's just Emma and her dad, and life is good, if a little predictable...until Emma is unexpectedly sent to spend the summer with her mother's family that she hasn't seen since she was a little girl. When Emma arrives at North Lake, she realizes there are actually two very different communities there. Her mother grew up in working class North Lake, while her dad spent summers in the wealthier Lake North resort. The more time Emma spends there, the more it starts to feel like she is also divided into two people.
