Frank, no ordinary sixteen-year-old, lives with his father outsIde a remote Scottish village. Their life is, to say the least, unconventional. Frank's mother abandoned them years ago: his elder brother Eric is confined to a psychiatric hospital; and his father measures out his eccentricities on an imperial scale. Frank has turned to strange acts of violence to vent his frustrations. In the bizarre daily rituals there is some solace. But when news comes of Eric's escape from the hospital Frank has to prepare the ground for his brother's inevitable return — an event that explodes the mysteries of the past and changes Frank utterly. Iain Banks' celebrated first novel is a work of extraordinary originality, imagination and horrifying compulsion: horrifying, because it enters a mind whose realities are not our own, whose values of life and death are alien to our society; and compulsive, because the humour and compassion of that mind reach out to us all.

A world that hangs suspended between triumph and catastrophe, between the dismantling of the Wall and the fall of the Twin Towers, frozen in the shadow of suicide terrorism and global financial collapse, such a world requires a firm hand and a guiding light. But does it need the Concern: an all-powerful organisation with a malevolent presiding genius, pervasive influence and numberless invisible operatives in possession of extraordinary powers? On the Concern's books are Temudjin Oh, an un-killable assassin who journeys between the peaks of Nepal, a version of Victorian London and the dark palaces of Venice; and a nameless, faceless torturer known only as the Philosopher. And then there's the renegade Mrs Mulverhill, who recruits rebels to her side; and Patient 8262, hiding out from a dirty past in a forgotten hospital ward. As these vivid, strange and sensuous worlds circle and collide, the implications of turning traitor to the Concern become horribly apparent, and an unstable universe is set on a dizzying course.

A little knowledge can be a very dangerous thing. Innocent in the ways of the world, an ingenue when it comes to pop and fashion, the Elect of God of a small but committed Stirlingshire religious cult: Isis Whit is no ordinary teenager. When her cousin Morag — Guest of Honour at the Luskentyrian's four — yearly Festival of Love — disappears after renouncing her faith, Isis is marked out to venture among the Unsaved and bring the apostate back into the fold. But the road to Babylondon (as Sister Angela puts it) is a treacherous one, particularly when Isis discovers that Morag appears to have embraced the ways of the Unsaved with spectacular abandon. Truth and falsehood; kinship and betrayal; 'herbal' cigarettes and compact discs — Whit is an exploration of the techno-ridden barrenness of modern Britain from a unique perspective.
