The Master is a benevolent tyrant, the world's sole immortal, whose 1000-year-reign has enabled him to steer humanity from an age of wars and want to a scientific age of peace and plenty. But now, the Master faces his greatest challenge ― for, what is the price of immortality, when Lady Ellora, the woman he loves, lies dying?

Then, Everling, a physician with a lust for power, offers to trade the Master a cure for the secret, planning to betray humanity and make himself dictator. It is a temptation only a God could resist ― her precious life against the world's security ― and the Master, though he has lived a thousand years, is still a man.

While the Master hesitates, it is up to two women to stop Everling: the Lady Ellora, and Tarmo, a naïf from a backwoods planet, who has history's greatest reason for wanting the Master dead!
