Harvard Professor Jonathan Weber is finally enjoying a season of peace when a shocking discovery thrusts him into the national spotlight once again. While touring monasteries in Greece, Jon and his wife Shannon—a seasoned archaeologist—uncover an ancient biblical manuscript containing the lost ending of Mark and an additional book of the Bible. If proven authentic, the codex could forever change the way the world views the holy Word of God. As Jon and Shannon work to validate their find, it soon becomes clear that there are powerful forces who don't want the codex to go public. When it's stolen en route to America, Jon and Shannon are swept into a deadly race to find the manuscript and confirm its authenticity before it's lost forever.
