The Art of Robert Frost on its US publication date. It is also available in the UK. The book combines 65 of Frost's poems with my introduction and detailed close readings, and has been beautifully produced by Yale University Press.
To cleanse the palette, let me finish by promoting someone else's work. Simon Turner has a new blog called Battle Lines, which will devote itself to 'the poetry, fiction, memoirs and journalism of conflict, from WW1 to the present day.' Highly recommended.
