I'll second that - a strongly positive review at Random Jottings of Margaret Forster's novel Over. It's far superior, in my view, to Unless by Carol Shields, though the two books share a common theme. The difference between them? The theme they share is that of loss, though the loss is more permanent in the one case than the other. But Forster succeeds in communicating the actual sense and atmosphere of it, whereas Shields describes a situation that would give rise to something comparable but - for me, at any rate - fails to convey the resulting feelings with any conviction or force.
