Mary Oliver is such a wonderful writer. Being a writer myself, I know that writing isn't effortless, but her poetry always gives me that impression - she has this very relaxed, almost meditative approach to the natural world that characterises her verse. It never comes across as laboured or formal, and it makes her work such a pleasure to read. There's actually a few lines in one of the poems here - "What We Want" - that talks about what people want in poetry: "something / inexplicable / made plain" (17), and it's such a great way of putting it. Oliver's language is not quite plain, I think, but it's approachable in the very best of ways.
