When Ruth Quayle used a special app to search for pictures of herself online, she found dozens of images of "Ruth Quayle" -- and one of "Ruby Starling." When Ruby Starling gets a message from a Ruth Quayle proclaiming them to be long-lost twin sisters, she doesn't know what to do with it -- until another message arrives the day after, and another one. It could be a crazy stalker ... but she and this Ruth do share a birthday, and a very distinctive ear.... Ruth is an extroverted American girl. Ruby is a shy English one. As they investigate the truth of their birth and the circumstances of their separation, they also share lives full of friends, family, and possible romances -- and they realize they each may be the sister the other never knew she needed. Written entirely in e-mails, letters, Tumblr entries, and movie scripts, Finding Ruby Starling is the funny and poignant companion to Karen Rivers's The Encyclopedia of Me.
