I started reading the Presidential Agent Series by W.E.B. Griffin when an online friend enthused over the 5th book in the series, "Black Ops". He said, however, that to really enjoy that one to the fullest, I'd want to read the first 4. I've done that, and have enjoyed them all.
This story built on the relationships that seem to grow more intriguing with each book. Castillo is an entertaining character, with his dog Max, his wise-guy comments, and his sly ways of cutting through the inevitable government red tape.
There wasn't a whole lot of plot to this book: the presidential order is to find and rescue someone. Most of the 400+ page book is about what the team goes through to plan the mission. The "action" all takes place in about the last 20 - 30 pages. The agents for whom the book is titled take up probably 5 - 10 pages of the story. Maybe less.
The author may have used this novel as a build-up for the next one. Although the plot was not nearly as interesting to me as earlier books in the series, it was still fun to read as the author painted a more detailed picture of Castillo, Pevsner, and other characters. I look forward to finally reading the book - Black Ops - that was originally recommended to me next!
