Finished Power of The Dog recently by Don Winslow. Fiction and painstakingly researched, about most recent drug cartels in Mexico, Central and South America, and southwest US. Brutal, well-written page-turner. Interestingly it hit the stores very close to when the Chief of Police in Nueva Laredo was shot a few months ago - same subject matter.

Currently:

Re-reading Bernard Cornwell's Sharpe series. Excellent historical fiction about British Empire in late 1700s and early 1800s - India, Iberian peninsula, France. This guy is a nut for research too and writes very well.

Daniel Goleman's Emotional Intelligence. Excellent benchmark work.
