Perhaps not quite as engaging as 2013's Here and Now, but Dunn remains as thought-provoking as ever. Marriage, old and new, remains a muse for him in poems like "Anniversary Poem" (obviously) and "For My Son." Death also looms in Dunn's mind throughout the collection. Thankfully, Dunn is also concerned with other issues beyond love and death. As he insists at the end of Lines of Defense's final poem: "I love the truth, / I swear I do."
