Who's That Girl?

Charlotte and Lottie have absolutely nothing in common – except they’re the same person.

Thirty-something Charlotte has a high-flying PR agency, a serious boyfriend and all the trappings of success – she’s living the dream, so why is it so stressful?

Twenty-one-year-old Lottie has just moved to London with dreams of becoming a writer. Carefree and single, she’s having fun – and on the brink of making some big mistakes.

So when a cosmic glitch brings Charlotte face to face with her younger self, she hatches a plan to teach her all the things she knows now: wear sunscreen, stay away from PVC trousers and Do Not Sleep With That Guy.

But what she doesn’t expect is Lottie has a few lessons of her own. And rewriting your past can seriously mess with your future . . .

Alexandra Potter’s deliciously funny and enchanting romantic comedy looks at life, love and what might happen if you could turn back time.
