Imagine if you could go back ten years and meet your younger self - would you recognise her? And what advice would you give her? Alexandra Potter's Who's That Girl? answers these questions when the situation becomes reality for Charlotte Merryweather. Firstly, she would be practical and tell herself to wear sunscreen, avoid PVC trousers and not give that idiot her phone number. Also, she'll remind her younger self that lemon juice won't bleach hair, it will just attract wasps. Oh, and he was the one - do not let him go! Charlotte is faced with a number of surprising consequences in this deliciously funny and enchanting romantic comedy that looks at life, love and what might happen if you could turn back time.
