The Fifth Domain
"A NASA scientist. A Russian hacker. A Secretary of State. What binds these people together? That’s the tangled web in which Peyton Stone finds himself. ... When a freak explosion at a California utility substation uncovers a connection to a brilliant but angry scientist, Peyton finds himself in Oman, Germany, and Russia piecing together the real story hidden deep in the covert cyber maze, on the hunt for the Russian Mafia genius who would exploit the world’s economy for his own personal gain."
