Virtuosic poems tracking two intertwined themes: the breakdown of an obsessive love affair and the vicissitudes of middle age. Invisible Dogs, Dempster's fourteenth collection, is a complex but deeply coherent hymn to the difficult business of staying alive. This is a book for when it hurts so bad you hope you'll die and are afraid you won't—not because it offers consolation or the promise of a new dawn, but because it so compellingly documents the plain, hard, ungraceful, stumbling grief of the matter, and meets it with rare self-knowledge, wry humour, and an unornamented determination to go on living. Dempster's metaphors are like hairpin turns taken at breakneck speed. He has nerves of steel when it comes to self-examination, and it's this relentless honesty and the emotional torque it induces that keep the voice on the road.
