The mark of any good story, for adults or youngsters, is how quickly you start to care about what's going to happen and the people it's going to happen to. This scores highly on both counts. By the end of the first page and a half, the question marks were in my head and I knew stopping wasn't an option. It's a pleasant surprise - and gives one a self-congratulatory glow at one's own perspicacity - to realise that this is a roman à clef, a rewrite of the Arthur myth with real people in place of the haloed Galahads and Lancelots, but the story stands on its own with no Arthurian props. Adventure, comedy, romance, escapes and escapades, heroes, villains, sages and oddballs - this has all the ingredients of classic historical fiction, Rosemary Sutcliffe for a grittier age. I can recommend it for all children, age 11 to 70.
