Smart money

In 2004, Boston author Ben Mezrich had a bestseller with "Bringing Down the House," the true story of six kids from MIT who played the system in Vegas and made millions. He followed that up with "Ugly Americans," the true story of a bunch of Ivy League kids who played the Asian stock market and made millions. His latest, "Rigged," is the true story of a kid from Harvard Business School who changed the oil market by helping to create the Dubai Mercantile Exchange, and, we suspect, also made a lot of cash. You can hear him read from "Rigged" tonight at 7 at the Boston University Barnes & Noble (if you're busy tonight, catch him tomorrow at 7 at Brookline Booksmith). Free.
