If you like thinking about things like this (DNA modification + War/Weapons + Gangs/Shaddy Governments), then I HIGHLY recommend the novel "Change Agent" by Daniel Suarez. He writes great one-novel stories that tackle complex topics about cutting-edge tech, and the Audiobook is excellently done too.
If you want to read a terrible book sort of along this line:
