The particular journeys of Half Life encompass New York, Havana, Berlin, Naples, Paris, Warsaw and Cracow among others, but Michael Ackerman has been on the path of erasing geographical and other distinctions for some time. It’s certainly evident in his earlier book, Fiction. Half Life continues the trajectory away from the constraints of reportage and the traditional documentary mode, but here the trip is even more personal and more unified. Documentary and fiction conspire with autobiography; all dissolve into hallucination.
