I finished the latest instalment of Alexander McCall Smith's The Importance of Being Seven earlier this evening (I was 3 pages from the end after breakfast).
McCall Smith's preface was one of the best I've ever read. He describes how in book signings all over the world, his readers' favourite character from the books is the ever-tormented Bertie Pollock. Bertie is 6, and has an exceedingly overbearing mother. He is fabulously endearing as a character, and is definitely the most compelling character in TIoBS.
Bertie, you will, one day, attain the miracle that is Seven. Until then (and probably afterwards), we will all thoroughly enjoy reading about your (mis)adventures.
