The R-master

by Gordon R. Dickson

"A repressively benevolent bureaucracy, intent on limiting and harnessing the effects of an IQ-boosting drug known as R-47, is thwarted by an underground led by an R-Master, latest of the drug-produced supergeniuses. Our hero's apolitical to start with but his chemically expanded perspective reveals the flaws in his superficial utopia. Energetically suspenseful, though the intriguing premise of an intelligence-enhancing drug might have been more fully developed."--Kirkus.
