Other Frank Herbert Books worth reading.

[Quazar]

There is another series that Frank Herbert wrote in which he created a universe of breathtaking span and depth. Unfortunately it only contains two books, or that is all I have been able to find.
These books deal with Jorj X. McKie, Saboteur Extadordinary. The first is 'Whipping Star', the second is 'The Dosadi Experiment'. I think they are extremly good books, very different and very complex.
