Who's That Girl? by Alexandra Potter Hodder, HK$94 Is it me or are novel titles becoming increasingly unoriginal? Exhausted after using cliches such as Be Careful What You Wish For and Do You Come Here Often? Alexandra Potter is thieving from songs and movies - and not very good ones at that. This does not bode well for the content and unsurprisingly Potter produces 'chick lite' books by numbers. Potter's heroine is (shock, awe) a journalist at a women's magazine. Or at least that is what Charlotte Merryweather was in 1997. By 2007 she (wait for it) runs an amazingly successful PR company 'formed three years ago by Charlotte Merryweather'. The plot borrows from time-travel narratives such as Peggy Sue Got Married and It's a Wonderful Life as Merryweather confronts different versions of herself. Two Merryweathers are more than any alternative reality could bear: a pair of overly enthusiastic media doves who coo endlessly. Merryweather is the sort of exhausting fizz-bomb who says 'Check' after listing the items she needs in her purse. When she imagines being pushed on a swing by her personal trainer, she says 'Weeee'. The end does not arrive soon enough.
