Flash Boys: A Wall Street Revolt

The main narrative involves Brad Katsuyama, a trader at the Royal Bank of Canada, a relatively obscure firm that is no where near the top tier when it comes to Wall Street trading. Katsuyama discovers that his trades aren't getting filled as he expects, and he becomes suspicious and goes looking for the problem. He ultimately discovers the world of high frequency trading, and the fact that the stock market is essentially rigged by firms that are able to use their speed advantage to game the system and siphon a little money off nearly every trade.
