When Emma's boyfriend Leo turns up at her special birthday dinner unforgivably late and horribly drunk, embarrassing her in front of her family, she decides enough is enough. Why can't someone just wave a magic wand over him and turn him into a reliable, considerate boyfriend? It would certainly save her a lot of trouble.

Soon she regrets wishing for a 'new' Leo at all. And, surely, Isobel can't be for real? One thing's clear, if Emma's going to win him back, she'll need to do some changing of her own...
