Overall I enjoyed this book - Herley has clearly put a lot of thought into how the penal colony of Sert operates. I felt there were a lot of similarities with Lord of the Flies, in terms of how the different groups on the island are characterised and interact with each other. The first few days Routledge spends on the island stand out as very visceral and brutal reading, and make quite a contrast with life inside Franks' village later in the book. Aside from my main criticisms, detailed below, I felt the ending was rather rushed and abrupt.
For me, Richard Herley's approaches to the issues of race and sexuality require comment as I believe they are detrimental to what would otherwise be a really great novel. I almost put the book down in disgust after the first non-white character is referred to as "a black" who, with the assistance of another, white, prisoner on the island, attempts to rape the main character.
Herley has addressed accusations of homophobia and racism levelled at him on his blog. His defences seem to be (a) that views held by a character in a novel don't always represent those of the author and that Routledge is intended to be seen as a bigoted and arrogant character whose views are challenged over the course of his time on the island, and that (b) the novel was written in a different time when different views prevailed with regard to sexuality.
I'm inclined to give point (a) the benefit of the doubt when it comes to race, as it seems to be only when characters are viewed through the eyes of the main character, Routledge, that they are specifically referred to by race. For me, this is the author showing Routledge to be a bigot upon his arrival at the island. That said, I was still shocked at the matter-of-fact way the character's racism was revealed.
Point (b) I'm less convinced by - especially since the author is still active and could easily go back and edit the more offensive parts of his writing. Gay relationships are banned in the village, a community run through a kind of strictly enforced paternalistic dictatorship that represents civilisation on the island. The main reason for this seems to be fears of the risk of AIDS, which the author notes on his blog was not well understood at the time of writing. While there is a subplot concerning a gay relationship within the village, and the main character's response to this, gay characters living outside the village seem to be presented as predators whose sexuality is expressed through acts of violence and slavery. Even the gay characters within the vilalge are characterised as putting the community at risk. Homosexuality seems to be used as at best a potentially harmful weakness and at worst a marker of predatory degeneracy and savagery characteristic of the dark side of human nature - a very disturbing characterisation that I don't think can be handwaved away as a product of different attitudes being prevalent at the time of writing.
This is a thought-provoking book that is worth reading, however the approach to sexuality would have been prejudiced and problematic even when the novel was first published, and has no place in 2013.
Herley still seems to be active and publishing - I'd say it's high time he revised this novel to correct the homophobic attitudes presented.
