Aidan Semmens’s fifth collection of poems moves from the range of the world to the deeply personal, always placing the detail in historical context. Employing a variety of poetic techniques, he moves from the moral ambiguities of empire to the run-in to Brexit; from a reworking, forty years on, of the poem for which he was awarded the Cambridge University Chancellor’s Medal, to the breakdown of language suffered by his mother after an ultimately fatal stroke.
