From meditations on the glimpsed and the fleeting — presences so small they “slip through cracks in the day” — to ruminations on some of the most pressing concerns of our time, the poems in Mark Roper’s new collection play a series of variations on how we perceive and try to connect with the ‘more-than-human’ world. There are poems addressed to familiar companions such as the moon, or a shadow (“your dark matter / neither life nor soul”); poems that stem from travels abroad; and poems that respond to the miniature worlds, and larger implications, of exhibits in a number of museums.
