Alexander was the greatest tyrant in history. His cruel, brutal and vicious reign struck fear in his enemies and allies alike. But that all ended when he was betrayed by his own people and beheaded by his archrival. As Alexander’s consciousness faded away all he could think of is all the faults he made, how he could have avoided them, how unlucky he had been, and his wrath and unwillingness to die at the hands of the man he hated most! But unexpectedly he was given not only the answers to these questions, but also a second chance to right all his many wrongs.
