Dark Energy was published as part of the Established Poets Series by The Grolier Poetry Press.
"Dark Energy is a spell binding event, a major new book from one of our living masters of formal (that is, musical) poetry. The immense sequence of "Gravity and the Black Hole" weaves fairy tale, classic myth, and modern psychology into a seamless tapestry, abounding in ironies and keen insights into the lives we lead. Moreover, a generous rasher of strong new Feirstein poems completes one of the standout collections of this or any other year"
