The Book of Fate is a 2006 novel written by Brad Meltzer.

In it, a 200-year-old code invented by Thomas Jefferson reveals a modern-day conspiracy that involves the power brokers of Washington, D.C and the elite of Palm Beach society.

[1] On a July 4th weekend, US President Wes Holloway attends an event.

The assassin kills one of the president's aides and best friends, Ron Boyle, and permanently disfigures Holloway with a bullet to the face.

In trying to figure out how and why Boyle has returned, Wes must piece together clues involving that July 4th, a decades-old presidential crossword puzzle, ancient Masonic symbols hidden in the street plan of Washington, D.C., and ultimately a 200-year-old code invented by Thomas Jefferson.
