BZRK is about two groups of people using nanobots to mind control people. The first group is called The Armstrong Corporation, is using the nanobots to mind control powerful people and then kill them. The second group is the BZRK team, and they are using biots to protect the powerful people from the nanobots. The BZRK team recruited to people at the beginning of the book, Sadie McLure and Noah Cotton. Both of whom have come across either the BZRK or the Armstrong corporation before. Noah’s brother was a part of the BZRK team when his biots, tiny nanobot like machines, used to help heal injuries, were destoyed, sending him into a state that caused him to go crazy. Sadie was at a football game when her father and brother’s plane crashed because the pilot was being mind-controlled.
