John Fagan, a well-known computer hacker, enters an on-line chat room in 1993 following the World Trade Center bombing, and proceeds to explain what mistakes were made that day and how he would proceed to inflict more damage and create a larger impact. Years later, when multiple planes are hijacked and crash into the Twin Towers and the Pentagon, he realizes that someone took his ideas to heart and are actually following through with them. John becomes a vital piece to a terrorist puzzle and one of the government's main suspects.

In lieu of the devastating day, September 11, 2001, the lax United States government jumps to action and one of the first items on the agenda is to enlist Jeannie Reese, a 22- year-old child prodigy currently working for the Pentagon. Jeannie receives a direct order to release her computer program IRIN, which hacks into every possible technology (e- mail, cell phones and any computer connected to the Internet) to find those responsible. When IRIN narrows the search to include a compound in Colorado, her own government turns on her and Jeannie becomes a fugitive. Not only is she running for her life, but she's also determined to stop those responsible for such terrible acts by racing against the government and her own program to find the truth behind the attacks.

WOW! This is a complex, riveting thriller that engrosses readers and intertwines them in unimaginable possibilities. I didn't set this book down until I'd read the last intriguing page.
