This is a collected but it's thin and her poetry is so consistent in both theme and style it has more the feel of a single volume. It can be said that over her career her work changes too little for her to be considered a major or important poet. That's a question for the critics who know more than I do. I like it that you can open this book up at random and find poems such as "Statue and Birds" and "Medusa" and "Night."
Night
The cold remote islands
And the blue estuaries
Where what breathes, breathes
The restless wind of the inlets,
And what drinks, drinks
The incoming tide;
Where shell and weed
Wait upon the salt wash of the sea,
And the clear nights of stars
Swing their lights westward
To set behind the land;
Where the pulse clinging to the rocks
Renews itself forever;
Where, again on cloudless nights,
The water reflects
The firmament’s partial setting;
—O remember
In your narrowing dark hours
That more things move
Than blood in the heart.
