@wetqaz huh. Feels like you could do anything with this. (I've literally just read it)
I can imagine 3 different scenarios:
1 - The DCP and a lot of the world succumbs to a zombie virus and the kids born within the past 17 years (because you mentioned 16 in the work) are somehow naturally immune to the virus without scientists knowing why, but it is extremely rare that anyone older than 18 prior to the outbreak has succeeded in living beyond that age without falling to the virus.
2 - kids are on the run, like others, because they developed supernatural powers and the DCP (mentioned in book) is a cover for experimenting on them.
3 - The kids are on the run because they are homeless and something went unbelievably wrong in their last foster home, that the situation seemed to focus the authorities on them, wrongly accusing them of being the culprits, when they are actually the victims of a crime scene.
Just some ideas for anybody who want to take this as their own if they can't figure out what to do with it ;) :)
