Zachariah Simon has the look of a scholar, the soul of a scoundrel, and the zeal of a fanatic. He also has Tom Sagan’s estranged daughter at his mercy. Simon desperately wants something only Sagan can supply: the key to a 500-year-old mystery, a treasure with explosive political significance in the modern world. For both Simon and Sagan the stakes are high, the goal intensely personal, the consequences of opposing either man potentially catastrophic. On a perilous quest from Florida to Vienna to Prague and finally to the mountains of Jamaica, the two men square off in a dangerous game. Along the way, both of their lives will be altered—and everything we know about Christopher Columbus will change.
