What Happened to Goodbye by Sarah Dessen

She still struggles with her relationship with her mom-who she doesn't want to see or talk to out of a sense of loyalty to her father-but she's starting to make friends, and even gets attached to Luna Blu and the staff there. Mclean begins to feel more comfortable in Lakeview. Later, Mclean gets a phone call from Opal telling her that her dad's been in an accident and needs his insurance card-she asks Deb for a ride to the hospital, and the two become friends. Riley and her friend Heather call Mclean over, and they eat lunch together-Mclean feels sorry for Deb, who is sitting all by herself. Mclean goes to school and is accosted by a peppy girl named Deb who claims to be the school's hospitality committee. She's also currently trying to put together a model of the entire town for the centennial, and needs help-Dave volunteers because he needs to do community service hours after getting caught with a beer at a party. The manager, Opal, resents Mclean's dad coming in and changing everything. In the meantime, things at the restaurant are going poorly. In every other town, she's gone by a different name and persona. She almost starts a new Ume.com (think: Facebook) account with a new name-like she does in every town she moves to-but instead decides not to. She hangs out for a bit and meets some people who are in her high school too, including a girl named Riley who is best friends with Dave, the kid she ran into on her porch. In the middle of the night, she hears music playing and goes out to the house on the other side-a college party house. She's startled to find a boy napping on their back porch, but he sneaks back to the house next door. When they get back to their new house, Mclean starts unpacking and getting everything set up. Her mom is still living in her old hometown, Tyler, with her new husband-basketball coach Peter Hamilton-and her new twin babies. They've just moved to Lakeview, their fourth move in two years ever since Mclean's parents divorced. Mclean and her dad are trying out Luna Blu, the latest restaurant that her dad has been sent to fix-up.
