Carl Dennis has become one of the most important American poets writing today. Unknown Friends, his tenth book, is about separation and connection, about actual friends we can never know fully and friends never met who are summoned into existence through the efforts of an imagination that insists on dialogue. While accepting our ignorance as inevitable, the poems work to expand the notion of what it means to be part of a community larger than any we can comprehend, both a community given to us by history and one outside of history through which the world of experience is nurtured and sustained.
