    Days is the grandest of department stores, whose security men are licensed to kill and whose seven owners, a group of very different brothers, brood in a penthouse, fetched endless vast meals by a grumpy butler. James Lovegrove's novel inhabits that realm where satire borders on allegory and realism is full of wild magic; it was, nonetheless, shortlisted for the Arthur C. Clarke prize. Security man Frank has reached a point of alienation such that he can no longer see himself in the mirror; Gordon and Linda have just got their first Days storecard, and are keen to undergo the Days experience; the Book Department's feud for space with their neighbours in Computers is about to enter a new phase. There are flash sales in Ties and Dolls, and a riot in Third World Musical Instruments. And who is sleeping in the Bed Department's four- poster? Endlessly inventive and savage in its humour, Lovegrove's novel will change for ever the way you feel about superstores, and gives a whole new meaning to the phrase "shop till you drop". --Roz Kaveney
