Tor Books, 2005
This omnibus collects all 5 volumes of the excellent, and under-rated, Demon Prince series by Jack Vance. Kirth Gersen is the sole survivor of the "Mount Pleasant Massacre" that was perpetrated by five arch-criminals known as "the Demon Princes." Each book follows Kirth as he tracks down and gets revenge on one of the Demon Princes. I have reviewed each of the individual installments elsewhere so I will just reiterate my basic impression of Vance as a writer in this series.
The books were written from 1964 to 1981.
