Just finished reading Steelheart by Brandon Sanderson, and The Moon Pool by... some author that is likely dead now. I am currently reading Black Mass at a friends suggestion. Black Mass is about the FBI (or a single section of it) protecting an Irish mafia boss in the Boston area from like the 70's through the 90's because he was an 'informant'. All about Whitey Bulger, Stevie Flemmi, and John Connoly the FBI 'handler' for the first two.
