This Fast Diet thing is obviously taking off - we've all got to look trim, slim and utterly fabulous in our bikinis this summer, right? Sadly my own 'Go on, have another slice' diet hasn't really done much for me, but hey ho. Charles Moore's biography of Margaret Thatcher is the first off the mark to cash in on The Iron Lady's passing - it's a hefty tome too, and only the first volume! Beach read anyone? Inferno is slowly creeping it's way up the chart: expect to see it firmly ensconced at the number one slot next month. Still hanging on in there is The Unlikely Pilgrimage of Harold Fry - a book I've only just read and one that I would recommend (see my review).
