Description:

This is the final book in the "Rings of the Master" series and describes the effort of Hawks, both to outwit the renegade pirates of the giant spaceship "Thunder" and to find the computer interface that explains the mystery of the five rings.

From Library Journal

The conclusion to the story begun in Lords of the Middle Dark and continued in Pirates of the Thunder and Warriors of the Storm. Jon Nighthawk and the crew of the spaceship Thunder face their greatest battle in the effort to obtain the last two rings they need to break the stranglehold of Master System and free the people of Earth. Chalker's talent for intricate plotting maintains suspense down to the wire in one of his finest sf series to date. Recommended. JC
