Life changes for Lizzy Swift when Claire Reynolds transfers to the Argyll School in their senior year. Claire is all Lizzy is not—reckless, independent, effortlessly cool. Claire introduces Lizzy to downtown Philadelphia—its clubs, parties, and vibrant art scene, and helps her get together with Matt, who Lizzy’s been crushing on for years. Soon Lizzy’s once-quiet life is full of adventure and passion. But Lizzy’s grades are slipping, and her new relationships are complicated. Sometimes Lizzy feels that she and Matt are soul mates, but other times he holds back from her. Claire can be moody and evasive, too. Lizzy knows her boyfriend and best friend are hiding things from her. Can what they have together last when the truth comes out?
