Friend. Lover. Imposter. Who is Cate Kay? Cate Kay is the most famous author on the planet. But it's just a name. Somehow, the woman behind the books has remained completely anonymous. Anne Marie Callahan is the name nobody knows. Annie knows there's no one left to connect the dots between the novelist and the girl who ran away all those years ago. If you asked, she'd say her name was Cass Ford. That's what her barista shouts each morning. And it's how she introduces herself to the woman she'll eventually call the love of her life. Three names, three lives. Cate Kay is finally ready to tell you who she really is. And when the truth is out, will everyone's favourite novelist hold on to her place in our hearts or are some betrayals impossible to forgive?
