The Secret of Fatima (Father Kevin Thrall Thrillers)

Father Kevin Thrall is chaplain to a poor, inner-city parochial school in Washington, D.C. where he leads a quiet and rewarding life. But he is also troubled by his past in combat with an elite military unit. Even after taking his vows, he is as ready to clasp his hands around the grip of a Glock as in prayer. He sometimes wonders who he really is.
To the Vatican, however, Father Thrall is uniquely suited for a dangerous mission--one directly tied to the mystery of a 100-year old prophecy.

One hundred years ago, the Blessed Virgin revealed a mysterious prophecy to three Portuguese shepherd children. The three Secrets of Fatima were closely held by the Vatican for decades, until the text of the third and last secret was finally released in 2000.
But many believe that the Vatican withheld important parts of the Third Secret, perhaps because its contents were too dangerous to reveal . . .

The Secret of Fatima's knife-edge plot unfolds as both a modern-day spy thriller and a spiritual quest, as Father Thrall faces implacable enemies both within and outside of the Church who will test both his unique abilities and his faith. If he fails, the very foundations of the world will be shaken.
