Nod by Adrian Barnes

A very interesting imagining of apocalypse by insomnia. Things fall apart quickly (too quickly?) once most people lose the ability to sleep in this Vancouver-set story. The readers get to follow the protagonist, a misanthropic etymology writer, as he navigates the sleepless new world, warring factions and all.
The real standout here is the writing, which is most impressive, especially for a debut. As far as I can tell, Nod was the late author's only novel, and it's a solid literary legacy to leave behind. A dour, depressing, descent into madness. Much the way dystopias are meant to be written.
At about 256 pages, the book is light, but it weighs heavily. A worthy read.
