An accessible book with a misleading title that provides a compelling account of the history and somewhat-current (2012) state of the stock market. My issues are that it reads more like an essay collection and doesn't get into enough technical detail (Algos, algos, algos ad infinitum). The author's attempt at piecing together a Lewis-esque narrative fell incredibly short, mostly in the way of character development. As was the case in The Quants, the book unravels in the last few chapters before an abrupt "huh?" ending. I think that Dark Pools is more valuable than Flash Boys in its educational value- I would go as far as pegging it a must-read. Granted, the people who I would recommend it to as a must-read to have probably already read it.
