Dr. Morgan Sierra is surprised by a late-night meeting with research assistant, Matthew Fry. Fry intends to take her back to the US for a project arranged by Dr. Everett. As an unwitting keeper of one Apostle stone, she finds herself in the middle of questions surrounding it, and its potential power when reunited with the other eleven stones.

Before their meeting properly adjourns, Sierra and Fry become the target of Thanatos, a group who wants her stone. They’re willing to take it be whatever force necessary. Because of her training in the Israeli Defense Force, she is not faint hearted, but a pistol-packing femme fatale who trusts few individuals. She and Fry blast their way out and escape.
Intuitively, Morgan fears for her twin sister's safety, knowing that she too carried one of the stones. When Morgan discovers her sister and baby niece are missing, Morgan finds herself embroiled in a search for the other stones to save their lives.
Although the story is set in modern times, it takes the reader on a whirlwind tour of the Mediterranean Region. While the story leans on Church history, Penn keeps the reader turning the pages.
I enjoyed this Pentecost immensely and think it reads like watching a movie. I can’t wait to see if Penn continues the adventures of Morgan Sierra. In the days ahead, look forward to reading more from this author.
