When Titans Clash — Robert Maxxim

The year is 125,000 BC. Bill Sullivan reincarnates in a small lake side village on Mars. Since early childhood, he demonstrates strong scientific aptitude and earns a place in the Martian Institute of Technology where he becomes a leading space engineer. He meets his beloved soul mate, Nei Lah, and both make plans to unite. However, he is tasked with helping Lemurians achieve space travel and leaves for Earth. But his ego and poor choices produce technology that is eventually used to attack and destroy Mars. Unable to deal with guilt, he leaves his people, and Nei Lah, behind and is lost to the wickedness of Earth for tens of thousands of years to come. This past, Bill must face and overcome, but nothing prepared him for an even graver past; his original rebellion against the Brotherhood, and the death of his beloved by his own hand.
