I don’t know Adrian Hon, but he has an amazing way of thinking. His website Mssv has an analysis of The Islanders of such fierce intelligence that I gibbered in the cupboard under the stairs for half an hour afterwards. It’s an analysis, not a review, and whether he liked the book or not remains unsaid.
His chart of the islander themes is as close to a map of the Dream Archipelago as I’d allow. (I execrate the inclusion of maps in novels, as many people know.) But Hon’s chart is just that: a kind of flowchart of the psychic connections between islands and islanders. While not endorsing it entirely (I’m not certain I agree with it all) I’m happy to pass it on, partly for your pleasure of encountering an original thinker. While on his website, have a browse around. A lot of interesting stuff there.
