Not Eternal explores the startling suffering and sentiment implicit in human mortality. At the heart of this collection, a son has died on the cusp of his first breath, but the book's stakes are larger and more universal than a single, silent, foreshortened life. Ranging from personal lyrics to monologues in persona, from triolets to a modified crown of sonnets, from surreal fantasy to natural landscape, George David Clark's poems sing of the brutality of time and the beauty that transcends it.
