The subtitle is Ben Bernanke's War on the Great Panic.  Here is one good excerpt:

For Ben and Anna Bernanke, excitement was jointly doing the New York Times Crossword puzzle nearly every day — although they skipped the easier beginning-of-the-week puzzles.  "That's the one thing we do together," Bernanke joked.  "It's shows our sexy social life.  We're pretty good.  We can do the Sunday puzzle in about forty minutes."

This is so far the most entertaining and most readable book on the financial crisis. The portraits of Bernanke, Paulson, and Geithner are especially memorable. Most of all this book brings those key personalities to life. It's also a useful chronicle of the sequence of events which led to the Fed taking on so many new powers. Recommended.
