Cate Kay is the most famous author on the planet. But it's just a name. Somehow, despite her bestselling novels and the record-breaking film franchise, the writer has remained completely anonymous.

Anne Marie Callahan is the name nobody knows. Only the people she left behind. And Annie knows there's no one there anymore who could connect the dots between the girl who ran away all those years ago and the famous novelist.

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. But 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?

Kate Fagan is the author of several New York Times bestselling non fiction books. The Three Lives of Cate Kay explores the cost of ambition, the longings of first (and second and third) love, and how it's never too late to go home.
