Incandescent prose. Beautifully textured characterisation. Transparent narratives. The adjectives to describe the writing of John Banville are all affirmative, and The Sea is a ringing affirmation of all his best qualities. His publishers are claiming that this novel by the Booker-shortlisted author is his finest yet, and while that claim may have an element of hyperbole, there is no denying that this perfectly balanced book is among the writer’s most accomplished work.
