The Nine tells the story of the Supreme Court over the last 20 or so years. Toobin gives an in-depth look at the personal histories that shaped many of the Court's landmark decisions in that period. I think one has to be politically inclined to really enjoy this, and I would warn conservatives that Toobin has a slight liberal bent. (He also writes for The New Yorker.)

Toobin's breakdown of legal procedures and theory is accessible without oversimplifying. He also does an excellent job of making the history into a cohesive narrative, which actually made this a real page-turner (button-pusher?) for me.
