Even more for the utopia and dystopia than many other forms of speculative writing, a fiction’s world is pivotal to a reader’s engagement. It can be elevated from a mere backdrop to the very (however disguised) subject of the book, its hook as well as its raison d’être; such a story’s characters are a means by which to explore and humanise the setting. The Museum of Second Chances imagines a society that is compelling and thematically rich. Its premise is a self-professed eco-utopia, but one in which inherited collective guilt is deployed as a spurious, semi-mythic justification for state power. This artfully plays with ambiguities in a genre that can sometimes overindulge gauche satire, if not bludgeoning didacticism. And even when exploring established motifs (genetic modification, revised official histories) it does so with an inventive wit that relates everything to its heroes.
