Jeff Aiken Trilogy

Second this suggestion. As others have noted his books probably aren't going to win any literary awards, but they are fun entertaining reads. There are some similarities in subject matter to some of Dan Brown's books, but Russinovich is a former Microsoft employee (and iirc he wrote the sys intervals suite of tools) so his are much more technically detailed, and accurate then what you would find in Dan Brown.

Mark Russinovich's Jeff Aiken Trilogy. If you're looking for a quality bestseller similar to Dan Brown books. Zero day, Trojan Horse and Rogue Code are all excellent novels. Some common themes include computer virus epidemics, cyber armies, cyber warfare, dangers of an overnetworked but undersecured society
