Book excerpt: Margaret Atwood presents a selection of poetry by Gwendolyn MacEwen, who first met Atwood in a Toronto coffee shop. MacEwen's poetry is by turns playful, extravagant, melancholy, daring and profound. Her work takes its inspiration from subjects as hard-hitting as the Hiroshima bombing and as humble as the peanut butter sandwich. It springs from a deep involvement with self and world.
