Flash Boys does not feel quite as revelatory  as some as his other works, perhaps because he is so good at what he does it almost feels like a schtick by now. This time Lewis is looking how trading on the stock market works in the digital age. You want be surprised to find that only a handful of people understand how the modern stock market actually works and they’ve rigged the system against the rest of us. Lewis’s protagonist are the even rarer souls that see this and try to fight against it. Fans of Lewis’s other works will enjoy this, and anyone who wants a very thorough breakdown of how High Frequency Trading algorithms behave are in luck. While Lewis writes for the general public, I imagine it helps to have some technical and economic literacy to follow the story. Descriptions of how computer programs manipulate trades in nano-seconds will, by nature, get a bit tedious. That being said, if you haven’t read Lewis there are more accessible and highly recommended works of his. Based on how fast technology moves, I have no idea if the information in this book is still relevant, but is illuminating to realize how little we understand about something that has such a huge impact on our lives.
