Poetry. Virtuosic poems for anyone who has ever survived a broken heart or made it past fifty. 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.
