I must admit this was the book that I read at the end of the Readathon, so my recollections of it are vague. Black Dogs is about a woman's encounter with two huge, menacing black dogs while on a walk in France. Her husband out of earshot, the woman is attacked by the dogs. She manages to fend them off, but her life and the life of her husband are deeply altered. For Bernard, the encounter was just an unpleasant event. But for June, the dogs are the incarnation of evil. This rift drives them apart, opening a large metaphysical gulf between them as she becomes a devout Catholic and he remains an atheist.
It is really hard to rate this book because I don't remember it very well. But I do remember my impression that Black Dogs was not as good as my previous McEwan read, Amsterdam.
