Book was good. Basically profiling the few guys on wallstreet(in particular one guy who's on the spectrum and managed to see it before anyone) who recognized the housing bubble and were able to profit from it. Not necessarily noble heroes, but they did try and warn everyone including the FED that the collapse was coming and no one listened.
Did a good job exposing how the banks, rating agencies, and the wallstreet thieves guild were all working together and turning a blind eye to their shady way of doing business despite the impending doom it was about to bring.
