Curious but quietly impressive near-future SF, set in a France under a far right government (of sorts) around the launch of a technology, '404', created with the noble objective of reestablishing 'truth' amid a crisis of distrust in media and an explosion of deep fakes. It all goes awry when the technology becomes a harbour for extremists, suicide cultists and sectarianism.
Behind the plot is the unrequited long term passion our protagonist has felt for his onetime classmate - the founder of 404 - a kick-ass Algerian-origin tech siren from a prosperous and integrated extended family. As a point of reference he's a pretty strong vehicle, as a bit of a drifter and ne'er-do-well who's credibly blank as an observer and very much on the sidelines. His age-long horn for 'Allia', the heroine, captures the dynamics of unrequited love very well: she's out of his league; she's married to someone far cleverer and he's the tea boy in the story, to some degree.
The novel's portrait of an integrated household and community-minded local mayor in is strong and the unfolding of the 'fourth generation' separatist movement in the anonymous, 'left-behind' provinces is very well told and a fresh take on the 'immigrant' story currently preoccupying French lit. It's satisfyingly ambiguous too: there's no neat arc, the crisis rumbles on and it feels perhaps that we're headed for a sequel (that seems to be Sabri Louatah's thing).
All told: an odd little number, but as an exercise in proto-Black Mirror thinking around tech and as an exploration of the immigrant mindset, it's pretty accomplished. '404' in itself would be a pretty great idea in a world of Qanon fuckwittery and Trumpism. Get working on that, techbros.
