He is called the Scottish Celine of the 1990s (Guardian) and a mad, postmodern Roald Dahl (Weekend Scotsman). Using a range of approaches from bitter realism to demented fantasy, Irvine Welsh is able to evoke the essential humanity, well hidden as it is, of his generally depraved, lazy, manipulative, and vicious characters. He specializes particularly in cosmic reversals--God turn a hapless footballer into a fly; an acid head and a newborn infant exchange consciousnesses with sardonically unexpected results--always displaying a corrosive wit and a telling accuracy of language and detail. Irvine Welsh is one hilariously dangerous writer who always creates a sensation.
