The Secret Code (Paperback) by Paul D. Meier,Robert Wise

For eight years, Judy, computer whiz Ben Meridor and Judy's strangely gifted brother, Jimmy, have been unraveling the code embedded in the Torah. Considered subversives by Israeli intelligence because of their warnings of an imminent terrorist attack, they covertly re-enter the country. What began as an engaging mathematical puzzle becomes a race against the clock to save Messianic Jews from the impending fulfillment of end times prophecies.
