Emma Saylor doesn't remember a lot about her mother, who died when she was ten. 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, her grandmother, and cousins 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 divided into two people as well. To her father, she is Emma. But to her new family, she is Saylor, the name her mother always called her.
