Posthumous Noon was selected by Jane Hirshfield as the winner of the 2017 Barry Spacks Poetry Prize from Gunpowder Press. Of the collection, Hirshfield said: "Posthumous Noon is a book of grief and its bearing. It is also a book of language's largess and leaping--as all true poem-volumes must be--and a book of the treasure house of the living: of largemouth bass; of the eros of moths and of humans; of cities and fields, stories and waters. It is a book holding as well many kinds of migration: the migration of the body in illness, of love's witness, of souls, of creatures, of aftermath. In word, music, and image, Aaron Baker confirms his book title's promise: even amid loss's darkness, the full dimensions of light cannot be kept from this world."
