Apocalyptia

Ed Sawyer, seventeen, is one of those ignored types at his school. A nerd hopelessly obsessed with all things cinematic, he lives for his next flick. He's matched by Linda Usher, a classmate who is also into movies, as well as computer coding and hacking. 

On the last day of school before summer vacation, Ed is given a flash drive by a dying man. He sees a code on it, and Linda, for all her genius, can't decipher it, either. They are soon pursued by not only domestic terrorists—ex-members of the Department of Defense—but also by Russian agents who are after the same thing. 

It seems that the creator of the program, Harry Haskins, devised it as the ultimate smart bomb, the ultimate tool for controlling the internet and every single computer program around, including those of defense. 

It's a secret that the wrong people will kill for, and Ed and Linda have to go on the run from those who would capture and kill them—and that includes citizens as well! 

Only Linda has the knowledge to prevent such a catastrophe from happening. The only question is whether the duo can remain alive long enough to deliver the goods to the right people.
