The book of fate - Brad Meltzer

In six minutes, one of us would be dead. None of us knew it was coming . . .

So says Wes Holloway, a once-cocky and ambitious presidential aide, about the day that changed his life forever. On that Fourth of July, Wes put Ron Boyle, the chief executive's oldest friend, into the presidential limousine. By the time the trip came to an end, Wes was permanently disfigured, and Boyle was dead, the victim of a crazed assassin. Eight years later, Boyle is spotted, alive and well, in Malaysia.

In that moment, Wes has the chance to undo the worst day of his life. Trying to figure out what really happened takes Wes back to a decade-old presidential crossword puzzle, mysterious facts buried in Masonic history, and a two-hundred-year-old code invented by Thomas Jefferson. But what Wes doesn't realize is that The Book of Fate holds everyone's secrets. Especially the ones worth dying for.
