This taut, true thriller dives into a dark world that touches us all, as seen through the brilliant, breakneck career of an extraordinary hacker—a woman known only as Alien. When she arrived at MIT in the 1990s, Alien was quickly drawn to the school’s tradition of high risk physical trespassing: the original “hacking.” Within a year, one of her hallmates was dead and two others were arraigned. Alien’s adventures were only just beginning.
