C.S. Lewis's dazzling allegory about heaven and hell – and the chasm fixed between them – is one of his most brilliantly imaginative tales, as he takes issue with the ideas in William Blake's 'The Marriage of Heaven and Hell'. In a dream, the narrator boards a bus on a drizzly afternoon and embarks on an incredible voyage through Heaven and Hell. He meets a host of supernatural beings far removed from his expectations, from the disgruntled, ghostly inhabitants of Hell to the angels and souls who dwell on the plains of Heaven. This powerful, exquisitely written fantasy is one of C.S. Lewis's most enduring works of fiction and a profound meditation on good and evil.
