During her long history, Seven Sisters, an aging antebellum in Mobile, Alabama, has been home to many troubled souls. Some never want to leave it - even after they're dead. Including Isla Beaumont, the cast-off child of an affluent family, a girl no one wanted to admit existed. Until the Cottonwood family needed her. If you've read Seven Sisters, you probably think you know Isla's story...but do you really? Ghost on a Swing is a Seven Sisters extra and can be read as a prequel.
