 It's a very different kind of linguistic ambition now from what I was after in "Death of a Naturalist" or "Wintering Out" or "North".Not all reviews, however, were favorable.In the "New York Review of Books", Al Alvarez calls Heaney an “intensely literary writer” and writes that the “reticence and self-containment” seen in "North" are not present in "Field Work"."
