I can’t imagine being a spy. Not being able to trust anyone even though sometimes you might have to if you want to survive would be awful. This had a lot of tense moments and our hero got shot…a lot! I really liked the interaction between Anya, an older and much more experienced KGB spy and Tyler, a younger and very inexperienced CIA agent. This is a short fast paced historical piece that I found quite enjoyable.

I listened to this and it was a shorter story than I usually do. The plot was ok as was the character development. I just don't think I enjoy shorter books. I like to really emerse myself in the story and it just was too quick with the plot. Easy read and interesting, I will definitely try other books by him.

Skip this unless you’re extremely bored or desperate. Disappointing.

I’m being generous giving it 2* instead of 1-5* which is pretty much where it realistically ranks.

This is definitely not a terribly believable spy thriller, in fact I’m wondering if the (usually adept) author has ever even read a single spy fiction tome before.

The Russian spy seems fairly experienced but even she does stupidly rookie things, presumably with the sole purpose of propelling the plot in whatever direction the author has chosen. And as for Tyler Wolf, I’ve never come across such a bumbling, inept spy in my (long) life and hundreds of spy literature consumed. He’s an annoying idjit.

Too many plain dumbass decisions to treat this as a serious espionage thriller, it’s mildly amusing in places but only due to the sheer idiocy on display.
I’m really not sure why I even bothered reading its sequel, maybe in the vain hope it would be an improvement. Sadly, it was not.

A different kind of Jack Mars book.

Tyler was very green for a field agent with the CIA and didn’t know anything about being a spy. Naya was a very experienced agent for the Soviet Union. Them working together was like a cat and mouse playing. He couldn’t keep up. She was telling and showing him what to say and do. By the end of the book Tyler was catching up and acting more knowledgeable about the spy game. The CIA just needs to figure out if Naya is going to be a double agent for the CIA and tell them information about the Soviet Union or give the Soviet Union information on the workings of the CIA.

Another new series by Jack Mars, this time set in post WWII Berlin, 1948. A rookie CIA agent, Tyler Wolf, is sent to Russia to get in contact with a female agent. She actually saves him from an attack and accompanies him to Berlin. There she tells him, she wants to work as a double agent. After consulting his boss, they both are tasked with hunting down a surviving nazi, who attacks the occupying forces in Berlin. Another interesting read by Jack Mars.

Average

Late 1940s spy thriller, CIA has just been created and is playing catch up against the Soviets
Tyler Wolf is a new agent, with very little clue and so much to learn, that gets teamed up with an experienced soviet spy, chasing the remnants of the Nazi party
The premise is ok, you can guess where the series is going, the only real question is, who is double crossing who and that may take a number of books to determine

First in a series

I like the author and came across this new series. It leaves the reader wondering and is good but not great. I am undecided about the second book - but I will likely try it and see if it captures me. The male spy seems naive, and I am not sure how that settles with me at this point.

Tyler is a lovely spy for the CIA. He sort of falls for Anya, the KGB defector. Together they avert a nuclear war. Tyler breaks apart the detonator in a mass rally much to the displeasure of the pro-Nazi Muller.
I loved the distinct and tasteful character of Tyler to an extent that made me inclined to award this book 5 stars.

Great Series Start

Jack Mars really knows how to start a series. Rookie CIA agent, very early stages of the Cold War, post war Berlin. Teams up with a Soviet spy. More to come. Definitely stay on for the wild ride!

Double Agent

Great story. If you enjoy stories of post World War II, this is the book for you. Two foreign agents from different backgrounds work together to blend their ethics to get their job done.

Jack Mars knows how to write mystery books that keep your attention. He builds interesting characters and keeps the action rolling. Since the books are a series, you tend to guess the outcome, but you don't mind because the action is so good.

an enjoyable read

I enjoyed the thrust of the story and the issues that both sides faced in post😄war Berlin. Unfortunately I did not think the writing was up to the standards of many other authors of this genre.

The book had a good story line, wasn’t thrilled with the AI voice. It was too monotone and found it difficult to keep my attention.

Didn’t love the AI narrator with the Max Headroom glitches. Story was OK but just that… OK.

Jack has once again hit it out of the park. Tyler Wolf and the beginnings of the CIA in post war Germany/Europe. Looking forward to the next!

read it in one setting

a book that did not falter in pace from the first to the last page.
The plot twisted and turned as it unfolded.
Skilfully written.

No depth to the characters. The plot is weak and the lack of any character development makes it a poor read.
