My recent favorites are

Never Split the Difference: Negotiating as if Your Life Depended on It - Chris Voss/ Tal Raz

Interesting info on negotiating.


The Dark Secrets of SHTF Survival: The Brutal Truth About Violence, Death, & Mayhem You Must Know to Survive
- Selco Begovic

Written by a man that survived the Balkan War, great read on modern survival when society goes south. It doesn't look like you think it would and it shows you what matters and what doesn't.
Look for the first edition, its a much better read than the later releases.
