Now Wait for Last Year

The man who could save the world was dead - again!<br/><br/>Once he had been assassinated by a political rival. The second time he had a heart attack while negotiating a surrender to the enemy. Now he was back, younger and more vigorous thatn before, giving new hope to the Terrans in their battle for survival. Had he really died once, leaving a robant in his place? Or had he learned to manipulate time so he could use all of his several possible futures?
