Alexander, Enigma (Alexander Galaxus Book 6)
Alexander is on the edge. As the Methuselans close in on the Galactics their fate is in the hands of an increasingly distant and volatile Overlord. Even as Alexander strives to maintain the hope of victory, his destructive genius is tearing at the very fabric of Methuselan civilization. Half a million years of 'Elite' hegemony is on the brink, but who will fall first the Methuselans or Alexander? Hanging in the balance is nothing less than the fate of the galaxy.
