This is the first in a series about the “Deathless”.
The premise is that somewhere in the future, a person creates nano-tech to give immortality to humans. It is done by replacing our existing DNA with an artificial DNA/biology.
This is the first in the series and is about what happens to the world after this all happens. The specific people involved are Lucius Sterling (the patent hold of this creation), Jack Sterling his grandson who is allergic to the technology, Leo Fontesca (Lucius’s right hand man and the actual creator of), Alexa who starts out on the brink of death but ends up much more.
Many others enter the story and big creations that one has to seriously suspend belief for are created for the story but the story movies and lots of action and interaction happens. It is compelling. I will look for the second book.
