In Purity of Absence, Dave Margoshes explores love in its waxing and waning, the extravagance of its fullness, the agony of its departure. Like an explorer charting new territory, he casts his eye on the rhythms and syntax of love, observing its aspects both quotidian and rare. The poems in this new collection, Margoshes's first in a decade, chart the ekg patterns of love, not just the mature love between a man and a woman but love for a parent, friends, knowledge, place and, ultimately, life itself.
