California politics in the 1960s was run by Governor Pat Brown and state Assemblyman Jesse Unruh, known to most as ``Big Daddy,'' a tarnished political boss who was loud and ostentatious. To Mills, he was a powerful professional with a reform agenda. Then a fledgling assemblyman who turned to Unruh for mentoring, Mills shows Unruh at work. His chummy, enlightening account gives a new view of the Brown/Unruh quarrel, which unraveled the Democratic club and led to Ronald Reagan's election. Libraries with an interest in state politics, especially in California, may wish to add this controversial book.Susan E. Parker, Harvard Law School Lib., Cambridge, Mass.
