Beyond This Horizon - Robert A. Heinlein

Hamilton Felix is the ultimate man, the end product of highly refined applied genetics in a world that has long since banished disease, hunger, and war. But no one counts on what happens when this superman is recruited by a cabal of dissident revolutionaries for their Glorious Revolution. They find out it is definitely not a good idea. Hamilton Felix, the result of generations of genetic selection, finds his life as the ultimate man boring, until a gang of revolutionaries tries to enlist him in their cause.
