"... I've learned to trust myself. I've learned that people --". Well, that wasn't quite right. She corrected herself: "Adults. Are just loosely connected. They're just a bunch of compulsions and stuff. Rationalisations. Seriously. Even before the Fall. Small things could break them. They're not like kids." (p. 128)
Shine was introduced as a revolutionary new medium for neurological directives: 'it makes you want something and it activates the neurochemicals to support the directive' (p. 145). It's the 'lightborn' of the title (though it seems to me that lightborne', carried by light, would be more accurate) and can confer both knowledge and ignorance: one of the characters uses it to conceal parts of buildings. The dissemination of Shine, which only works on adults, was controlled by an AI: then the AI went rogue, leaving the adults 'trapped by mental patterns they couldn't escape' (p. 39). That was the Fall, which happened on 19th July 2004.
Two years after the Fall: Los Sombres, a city somewhere in America, is allegedly inhabited solely by flesh-eating zombies and militant DJs. Or so Xavier is told. On a quest for a new supply of kisspeptins -- which delay puberty, and thus protect against the bad Shine which has zombified all the adults of Los Sombres -- he discovers that things aren't quite the way that the adults in his life have presented them. For one thing, his faith in machines -- "too honest to fuck around with your head" -- is severely shaken by his first encounter with the evacuator robots.
The other protagonist, Roksana, is in her late teens (past puberty) but is impervious to Shine. Perhaps this is somehow connected to the identity of her father, a pioneering researcher in the Field of Shine. Roksana -- and her sidekick, the precocious Elsa -- are engaged in a kind of guerilla warfare against Shine and its agents, trying to help the afflicted adults help themselves as well as protecting them from the robot (and human) guards who enforce the quarantine.
And into the refugee community, which is organised by the local Native American tribe, comes a stranger from Los Sombres, and following his arrival everything starts to change.
Sullivan doesn't believe in easing the reader into her alternate 2006: we dive straight in at the deep end, almost overwhelmed by strangeness and slang. All (or most) becomes clear as we read on.
It's a small apocalypse, and extremely localised. The rest of America -- the world? -- waits, unaffected (their Shine hasn't gone rogue) and apparently happy to keep Los Sombres quarantined until all the zombies are gone.
There's a lot here about parents and children, and children parenting their parents. Sullivan's focus on her adolescent protagonists makes this rather more than 'just another zombie apocalypse'. Roksana and Xavier are tougher and less broken than most of the adult characters. Their voices are convincing.
This isn't my favourite of Sullivan's work -- in particular, I find the ending rather weak -- but it's full of gorgeous pacy writing, cool ideas and cinematic descriptions of everyday life after the Fall.
