Whenever invited to talk about her career, SH invariably says that she had always wanted to be a journalist, was only a make-up assistant etc as a stop gap. Anyone aspiring to be a journalist would, I imagined, aspire to be the next Woodward and Bernstein or Harry Evans or Lois Lane - but I imagined wrongly.
In one article (or maybe podcast) that I came across quite recently she was clear that the career she had in mind was as a women's magazine journalist. So, not slogging away on the newsdesk or following up leads to get her next big scoop, but writing articles about fashion and beauty and other areas of 'women's interest'. That's what I think the book will be - a collection of the sort of articles she saw herself writing for women's magazines in the 1990s.
Growing up, I loved magazines too. I'd count the days till the next issues were coming out. But that was then. I don't imagine the book will be as bad as that review makes out but - based on the pre-publication publicity - it does sound as if it might have been written for another era.
