The Raw Shark Texts
Steven Hall

Some context, from 9 years later:

Back when I wrote Goodreads reviews, I tried to keep them short & sweet โ€” which makes them seem a little out of place here on this blog!

Took me a while to get into it, but the concept is excellent and Hall doesn't assume the reader is an idiot - I get the feeling I'm going to need to read it again and hunt down the unchapters thoughโ€ฆ
