I read this book as part of my 2016 (and on) reading challenge--the one where I asked people to recommend something that I should have read that I might not have encountered. This was recommended by a friend of a friend, who was too shy to post on my Facebook wall.
This is in no way a nice book. Written by an author with an intimate knowledge of the setting -- institutions for the criminally insane -- one presumes that the level of detail is accurate, although whether it is poetically exaggerated, condensed in time scale, or just presented as a highlights reel might be left to the reader to work out. There are few, if any, sympathetic characters, and there are aspects of the language use that have fallen out of favour, and as such I found threw me the first few times because they felt forced -- as if the author was including them for shock value.
The book consists of two novellas which were originally published separately in Australia, but bound together for the overseas market. Both novellas are written predominantly in the second person, a conceit which I would usually argue doesn't have the narrative strength for a piece such as this, but which works well, as it brings the unpleasantness closer, makes it more visceral. Early in the book I found it difficult to accept that the setting was the 1970s*, as some of the aspects of the treatment of the inmates feels more in keeping with material set earlier. This is presumably related to my lack of knowledge, rather than anything else, given that my learning about such treatments occurred in the mid-1990s. But there is extensive use of electro-shock therapy, to quite unpleasant levels (and with significant non-consent from the patients), a practice that I believed had not lasted to that degree quite so late.
Is it a good book? Yes. Do I appreciate having read it? Yes. Did I enjoy it/want to recommend it to people? Not sure.
But if one wants to get a feel for the treatment and (lack of) understanding that psychiatric patients (and in this case, this includes individuals with significant intellectual disability as well) received, this is a much better choice than, say, the voyeuristic book by Oliver Sacks that I also read.
* and I'm still not convinced. I'd need to check, but the publication date is 1980, in which case the setting must be at most the 1970s, and might be the 1960s, which might work better in with both my understanding and my prejudices.
