"Mark came to Microsoft in 2006 to help advance the state of the art of Windows, now in his latest compelling creation he is raising awareness of the all too real threat of cyber terrorism."
"CyberTerrorism. Get used to that word and understand it because you're going to see more of it in the newspapers and hear it on the news in the not too distant future. Mark Russinovich is a CyberSecurity expert who has turned his considerable knowledge into a very scary and too plausible novel. Zero Day is not science fiction; it is science fact, and it is a clear warning of Doomsday. A must-read for all Americans and for those entrusted with our security and our survival."
"While what Mark wrote is fiction, the risks that he writes about eerily mirror many situations that we see today."
--Howard A. Schmidt, White House Cyber Security Coordinator
"An up-to-the-moment ticking-clock thriller, Zero Day imagines the next 9/11 in a frightening but all too believable way. An expert in the field, Mark Russinovich writes about cyberterrorism with a mix of technical authority and dramatic verve. I was riveted."
--William Landay, author of The Strangler
"When someone with Mark Russinovich's technical chops writes a tale about tech gone awry, leaders in the public and private sector should take notes."
