This winter’s blockbuster book in the UK? A book on punctuation – Lynne Truss’s Eats, Shoots and Leaves: The Zero Tolerance Approach to Punctuation. “Demand for the book has been so great it burned through six printings in the first three weeks of publication. The initial print run of 5,000 ballooned to 510,000; in the second week of December alone, 67,000 copies were sold, beating sales of John Grisham’s new book by more than 40 per cent. Seems correct punctuation isn’t just for your pedantic parents any more.”
