Acclaimed poet David Cope's fifth collection, Turn the Wheel, opens with a lean dawn, farewell to old loves and challenges to new, past sorrows and tenderness filling the older poet's dreams, tender petals for calm crossing. Here too is ground zero struggle for compassion, lost worlds in the valley of the sun, finale a broken note, herons under the jetliner's blast path near the shaking train stuffed with its cargo of dead dreams.
