From the book's introduction Not every Pathfinder Roleplaying Game character is built to take challenges on using direct assaults — some prefer subtler methods that focus on stealth, misdirection, and covert maneuvers. The Genius Guide to Feats of Subterfuge contains a collection of feats that provide new alternatives to characters who use duplicity and deception to make their ways through the world, including exactly zero feats that add a +2 bonus to a pair of skills (so we can focus on other interesting options).
