Diablo, The Sistema Series Book Four (ebook)

Within every man is a devil. There is only one Satan.

Vangelis Zervas has just been subjected to the most insidious psychological program ever invented by man. He comes out of it in a coma, sequestered in the Medical wing at Vathos systems. Maddox Maynes, his supervising officer, has also returned from their encounter in the Inferno program, still conscious but carrying something deeply sinister within him. The reverberations of the program are carried from the virtual into the real, as Vathos is shaken from within by perhaps the greatest enemy it will ever face. This is the beginning of the end.
