Pope Celestine asks his friend Cal to investigate The Fourth Prophecy of a celebrated prophet. Another group is after the same prophecy. Cal travels over Europe trying to get answers. It's an action packed thriller.

This is a whole lot of Catholicism, well written , well researched and thrilling. I personally got a little bogged down in it since I am not that familiar with the workings of the Catholic church but the text was enlightening. It was a good story.

Another great Glenn Cooper book.
Loved this story with all its twists and turns that kept me turning the page all night. The story takes the reader on a journey through many amazing places, all while the characters race against the clock. Had a slower start than his other books, but took off after the first few chapters and didn't slow down again. Highly recommend.
I received an advance copy of this book in exchange for my honest review.
