The Farm by Charles Anderson
I had read book 4 in this series and loved it so much I went and bought the first 3 books and just now getting to them.
This story starts out with Josiah and his buddy Andy exiting a crashing helicopter but he doesn't make it. Carlson will still continue the mission and does on his own but doesn't find what he was expecting.
Later he's at his night job in the US at the ER and he comes across a few Saudi Arabia princes who have been beat up-they will be returning home now that classes are over for the summer months. Problem is his RN Lindsey will be going with him to the farm for 3 days and they discover something not quite right.
Thing is we hear Lindsey's side to the story also and Andy is clueless, so far but he knows things are not adding up.
Love all the technology, weaponry and discovering the hidden treasures at the farm. Love the history in this book about the area.
Lots of action, travel, adventure and romance and I learn so much about things I don't have a clue about. US and other countries are involved and he is gathering the clues to solve the mysteries.
