If you like true-life spy stories, you'll probably like this book, but you'll also might find it thin gruel since it's not connected to big events and most of the story builds up to the writers leaving the CIA. They don't write about catching any bad guys or stopping terrorist tasks. Maybe they did that, but they just can't talk about it. They were as coy about it in their Fresh Air interview too.
The problem with any book from former members of the CIA is that they can't give you the real dirt, and even if the CIA doesn't censor the book (see the fight over Operation Dark Heart: Spycraft and Special Ops on the Frontlines of Afghanistan -- and the Path to Victory, for instance), the authors self-censor. I have no problem with that and I recognize that importance of it in the real world, but while reading the veneer of stories that any former-agent tells, I am constantly wanting to know more about what is going on, and I'm never satisfied. But, that's the genre. The book is short on operational details, and that extends even to the start of their personal relationship and Bob's seemingly sudden decision to leave the CIA, their divorces, and many of the other pivotal moments in the story. Even when they are out of the CIA, they can't let on too much about their lives. The book is mostly the highlights.
This book alternates between chapters by Bob and Dayna. For the first half of the book, their stories aren't connected. Bob is doing something in Central Asia, and Dayna is starting her career in the CIA protective services. Eventually there stories converge, and when they do the CIA portion is mostly over. Much of the book is matter-of-fact, as if everything has the same importance, or nothing is important. Just reading from the book, you'd think that one day he was in and the next day he wasn't. He doesn't go much into everything that led him to resign. He doesn't say much about thinking about "Riley", Dayna's codename, until one day he runs into her at Langley and asks her on a ski date in France. All of a sudden they are a couple. There's not much conflict or tension in their stories, like Mary Matalin and James Carville let go in their alternating chapters in All's Fair: Love, War and Running for President. The only thing they offer is that Dayna didn't like the car Bob first picked her up in and that Bob didn't know if they should get a third dog. There must be a lot more that we don't get to see. They do say that CIA couples have the advantage that they can at least talk to each other about work.
Dayna's story starts with her doing background checks, then being selected for the protective services. Bob's story starts with him already operating in Central Asia. There's not a lot of background, but Bob may have left most of his story to his earlier book, See No Evil: The True Story of a Ground Soldier in the CIA's War on Terrorism. Those are the details I find most interesting, but this isn't a memoir of their careers; it's the part of their careers where they overlap.
The most disappointing part of the book, however, is that the tidbits that these authors do let us see aren't really that important to the layperson. They aren't writing about super secret fieldcraft schools, they aren't writing about chasing bin Ladin or Carlos the Jackal, they aren't writing about stopping events that we've seen on the news, and they are in places where the bad things have already happened. The lure of the spy book is that we think they are doing those things even if they aren't telling us they are. Like the people they deal with after they leave the CIA, we want to believe in a cloak-and-dagger world of secret conspiracies and power that doesn't exist.
Bob starts the last paragraph in the book saying "Nothing I did in my years in the CIA added or subtracted from the mess out there". At the end of the most exciting event, where one of Bob's agents is shot, Dayna ends her part of story with "Another thing I think most people would be surprised about is that in espionage, few mysteries are ever solved" to explain that they never found out why the agent was attacked. Those two statements are the best summary of the book, no matter what the real story actually was.
