Christopher Coleman-Craig’s new book of poetry, Gods Love Murder, is an exploration of the common ground found in faith, love, sex, violence and silliness. He voyages throughout the world encountering many languages and traditions. John Berryman and Dr. Seuss are his main influences, as well as, Celtic religious belief, Biblical teachings, Hebrew Scripture, The Ramones. His intense interest in today’s human condition, which necessarily involves love, war, sexuality, politics, disease, children, fairies, little folk & more is what keeps me happy.
