My Evolution System and Fall from Space

Earth is dying. 

The System is the only lifeline.

On his 18th birthday, Grayson Reese expects a celebration on the Ring. Instead, he gets an injection of nanites, a neural lace, and a one-way trip to the ruined surface of Earth. His gift? An Evolution System capable of rewriting the genetic code of any living thing.Stranded on a hostile volcanic island, Grayson has to do more than just survive; he has to rebuild the biosphere from scratch.But he isn't just growing plants. As the mechanical contagion known as the Triad consumes the planet, Grayson must engineer entire civilizations to fight back.

 From the stoic Dwarves of the asteroid belt to the bio-luminescent Elves of the rainforest, he is building an army of new life.The old world is gone. 

Grayson has to code a new one before the Triad deletes it all.
