Love Is a Missing Person — M.E. Kerr

A Long Island teenager reunites with her older sister in a novel about family, sibling rivalry, and the love you didn't know you were missing

Fifteen-year-old Suzy Slade's parents are divorced. Now Suzy lives with her mother in a beautiful house on the ocean in Seaville, Long Island. Her gorgeous older sister, Chicago, lives with their father in New York City. At least, she did. Chicago just roared into town on her brand-new Harley.

With her sister's return, Suzy's whole world changes. She becomes caught up in Chicago's life -- and a secret affair she wishes she didn't know about. Her dad's been keeping secrets, too, and soon Suzy discovers the reason for the bad blood between him and her sister: his new girlfriend, Enid, who's only two years older than Chicago. Then there's Suzy's teacher, Miss Spring, who's pining for a lost love. Somewhere in the mix is Suzy herself, who's in danger of losing her own identity. It isn't until someone close to Suzy disappears that she realizes it's time to start living her own life.
