A secret so explosive, the church always insisted it was just a legend. Now it'll stop at nothing to prevent its discovery...

The coded journal of Benjamin Franklin. A hidden map. A legendary gospel. These are the first pieces to an ancient puzzle so powerful, it could destroy the very foundation of Christianity.

Once before, Joseph Koster unearthed one of the church's most deeply buried secrets . . . and it almost cost him his life. But some treasures are too hard to resist. And as Koster puts the pieces of the puzzle together, he discovers something even more startling . and infinitely more deadly.

Now, along with a beautiful engineer, Savita Sajan, Koster must race to decode Franklin's journal before it falls into the hands of those who would do anything, kill anyone, to suppress it. But in a world of secret societies, ancient conspiracies, and Masonic puzzles, locating the prize is one thing . staying alive, another.

For as Koster and Sajan are about to learn, the same key that unlocks the doorway to Heaven . could open the portals of Hell.
