Hi I read the first of what I presume is a series at a time the second book was not published. First probably 2016? I have since forgotten the author and title.
Plot... Experiments in hard wired brain stimulation leads participants to unexpectedly unlock the brains capacity for various 'powers'. Different subjects express these new powers in different ways. Government agencies seek to control these individuals but they fight back by taking control of a military stronghold in a mountain.
There was a girl that had unique abilities amongst the several factions that appeared. At the end of the book that I read she was kidnapped. Does this ring a bell with anyone? Thanks.
