These poems offer a rich series of impressions of the speaker's present life, surrounded by family, a garden, and pockets of natural life that evoke memory after memory of a childhood lived in relative poverty with a father whose years as a coal miner damaged his lungs and finally killed him. Allusions to his chronic and worsening illness and his death thread through the poems like a long shadow.

Recurrent images of his blood-stained handkerchief, his coal-smeared face and hands, are echoed in images of the death of an uncle, the deaths of animals, and of a mother strained by poverty and taking frugal measures to preserve small things. The final poem in the collection recalls her in old age, barely able to see, but still "stitching it all together."

The title poem, one of the best, pauses over the famous idea that the flutter of a butterfly's wings might be the source of large effects continents away. Together the collection invites us, without sentimentality, to consider how things are connected over time and come together in memory in compositions one couldn't have anticipated.
