Through the course of numerous books, Samuel Green has established his primary poetic preoccupations, and in Disturbing the Light, he continues to mine them, addressing rituals and work in a small, isolated, rural community; the influence of the past on the present, especially in families; and the nature and evolution of a love that has spanned five decades. Added to these themes is something new: Poems written in response to symptoms of late onset PTSD. Though Green’s Coast Guard service in Vietnam ended in the fall of 1969, memories have returned recently in vivid, disturbing details, amplified by the haunting knowledge that civilians in Southeast Asia are still, today, suffering death and injury from unexploded ordnance left over from that war. A powerful collection that reminds us that our past is always with us, even as we attend carefully to the present, Disturbing the Light is a masterwork from a poet at the height of his powers.
