Rebirth of a Marine

Just days Before his retirement, Marine Major General Stanley Petersen is severely injured and suffers a fatal heart attack while watching the famous Friday night retreat parade ceremony at the Marine Barracks in Washington DC.
Despite his utter certainty that he had died as a result, General Petersen wakes up at Bethesda Hospital very much alive but in the young body of another Fatally wounded Marine and is dumbfounded by this fact.
He quickly discovers that his body and mind had served as a host to a very unusual old Entity for decades, and that in its wish to have his mind survive had transferred it into the dying young man while repairing his body and bringing it back to full health.
Major Dan Evens, as he is now called, is recruited to foil an Al-Qaida plot to create a West Coast 9/11 mission since he had gained many years of experience in finding and eliminating such operatives, but never on such a scale. He uses all the unique powers that he had inherited from the Entity that he had hosted for decades to thwart the Jihadist mission and establishes himself as a premier anti-terrorist combatant for the US Armed Forces and the CIA.
