Following The Guidman's Daughter with his poems on Mary, Queen of Scots, Marsh begins this new collection with a sequence exploring the life and times of John Knox, locating this ambivalent figure in the turmoil of the Scottish Reformation. Marsh moves via Kepler and Darwin into a celebration of nature, searching within our secular world to 'find a language' to render its mystery and concludes by touching on the great challenges we now face. Our striving to understand the nature of things hints, perhaps, at the possibility of a different kind of redemption.
