If only you knew then what you know Imagine if you could go back ten years and meet your younger self - would you recognise her? What advice would you give? Wear sunscreen. Back away from those PVC trousers. Don`t give that idiot your phone number. Lemon juice won`t bleach your hair - it just attracts wasps. He`s The One - don`t let him get away. For Charlotte Merryweather, there`s no need to imagine. She`s about to find out for real. With some surprising Alexandra Potter`s deliciously enchanting romantic comedy looks at life, love and what might happen if you could turn back time.
