The follow up to her award winning Just Kids, mostly about her friendship and relationship with Robert Mapplethorpe, M Train is a kind of literary pastiche of her whole life, a fragmented series of incidents and stories, most of which carry the echo of her grief at the death some years before of her husband and muse Fred "Sonic" Smith. It's a beautifully reflective book, illustrated with her enigmatic photographs; not chronological or conventional, bit probably more profound as a result. A powerful, moving work.
