Grandfather Anonymous (Old Code Book 1) Kindle Edition

4.1 4.1 out of 5 stars 282 ratings

Elderly, unarmed, and extremely dangerous.

Ajay Andersen was the best hacker the NSA had ever hired. He sank corporations, toppled governments, and broke cryptography. All of it. Retirement hasn't slowed him down one bit, thank you very much.

His granddaughters are threatened, and he's going to need to step it up a notch. Biotech corporations and criminal enterprises hold the keys to survival, but ubiquitous surveillance threatens to reveal Ajay’s every move. Ajay would do anything to protect his family, but the more he digs, the more he dredges up the shadows of his own dangerous past.

He only needs to know one thing:

What makes his granddaughters so darn dangerous?

    Regrets? Ajay Andersen has more than a few. One of them is his estranged daughter Sashi. After 20 years on zero communications, he learns in Chapter One that she is a wanted fugitive, on the lam with her two daughters (wait! Daughters? He has granddaughters?). She is alleged to have stolen something valuable.

    Sashi promptly shows up on Ajay’s back doorstep. She asks him to watch his granddaughters for “a couple of hours.” But the “couple of hours” stretches way past that, and violent men shove themselves into Ajay’s world. He may not have known about them before, but the girls remind him very much of Sashi, and he discovers that he would do anything – anything – necessary to protect them.

    Even when they themselves must run for it. And even when it becomes apparent that the girls are far more strange and dangerous than they seem at first. This is a fast-paced thriller set in a hazardous future that gives readers little time to catch their breath. I quickly became engrossed in Ajay and his granddaughters, and I enjoyed every twist and turn in this first novel of the Old Code series.

    The book had a great opening premise, that of the digital world becoming the controller for the physical world, and that an old school hacker/programmer could and would seek a method and mode of staying away from the people and places that would act in a way similar to an elephant stepping on a spider-- with "the old guy" being the spider.

    The premise was that data transfer was based on a cube increase rate in technology, which is logical, but without a strong time frame for the increase it is more like the computer to computer 300 baud transfer of information compared to the internet. It is a long time since I was thrilled by a 300 baud modem, and using long distance to call another computer and allow exchange of tasks or information, but it reminds me that progressive doubling or cubing of performance is time frame related, not just hardware related.

    Yes, a lot of old men refuse to understand things, but I doubt any of the early guys really grasps the levels of the code and tech used today, so I wound up feeling like I was in the middle of a story about magic spells and wizards instead of super geeks and technology.

    It was entertaining, but it went too far in terms of the technology destroying the social structure, and of just how much an old man can really coax his body into doing-- or even thinking on the subject.

    It was good, it was interesting, too much padding and cute language instead of driving into the core of the story, but if you can accept it as magic and wizards creating a new super wizard, then it works.

    Four stars out of five stars if you allow magic and wizards to set the bounds of the story, it would be lower if you demand more accountability to linker interlocking limiting the increase in what tech cand do at what point.

    I vote for take it as updated magic, four stars worth.

    I really liked this book on science fiction in the future. If anyone who likes science fiction, they will love this book. It's in the future of technology and about how bad big
    can get about surveillance. With drones in the air above us to

    having big things, they call thunderhead, which can strike to kill you.

    The promise was good but not executed as well. The book didn’t grab you right away. It was slow moving and at times could have used a injection of action. It wasn’t awful but I won’t read this author again.

    Sometimes we just need to stretch and reach for an unusual genre as a reader. I did just that with the Cyber Crime/Biotech by Anthony W. Eichenlaub, GRANDFATHER ANONYMOUS. Admittedly, the main character being a senior citizen is what captured me, that and the fact that he was a computer geek. In spite of the fact that I was sometimes lost in the ultra-high tech terminology, the constant suspense and action kept me flipping pages at a determined pace. Seventy-year-old Ajay Andersen retired from the NSA as their elite hacker, but he didn't stop what he loves to do. The year is 2045, and the U.S. is a very high-tech society now, but also a very watched one--even by drones on various levels. (Frankly, I found the "watched" idea very disconcerting and quite possible.) When his estranged daughter suddenly reappears after a twenty-year absence with two granddaughters he never knew he had, Ajay's world begins to move at a pace his body cannot keep up with, but goodness knows he tries when he must protect those girls! It was a very interesting story that was not easily unraveled. I liked it a lot as something very different for me to read. If I were to be critical, it would only be to the writing in that it was extremely repetetive with the detailed aches and pains of Ajay, and the constant references to distance using golf terminology was very trite and aggravating. Also, he explained his poor fatherhood too many times. We get it already! Being redundant is not a good thing to the reader. Overall, a good story. I don't think I would pursue the series though.

    3.0 out of 5 stars Grandfather doesn’t live up to the hype
    Reviewed in Germany on September 22, 2023
    I like stories that are plot-driven and there is a nice line of plot to follow here. But what keeps a reader interested in the plot is a balance between the events and the WHY—the explanation of why these things are happening—and the inner workings of the characters. Sadly, there is too much of the backstory withheld from this first book in the series. The author piqued my interest in the main character from the first paragraph, and then limited how much my knowledge of Ajay developed so it was frustrating. I assume the author saved a great deal of information in order to preserve the discoveries Ajay and Kylie must make as they continue their quest in the future books, but that only works when the reader feels fully immersed in the world of the story. The other characters, especially those essential to the development of the plot, needed much more than the given hints of their natures. But what truly annoyed me was the constant references to golf—I have little interest in that sport so I have no understanding of what a 5-iron distance might be, or how far away an object hit by any particular club could be. Perhaps it’s an ineffective attempt to establish Ajay as a dedicated golf fanatic. Golf aficionados might appreciate this trope as clever, but people like me will not be buying the rest of the series.

    Thought this may feature a smart, physical grandfather ie. Like Clint Eastwood. Instead he was a bumbling wreck. Couldn't work out what type of world he lived in and what was the threat? Citizens were spied on, but for what purpose? Couldn't get into this.

    5.0 out of 5 stars I loved this book.
    Reviewed in Australia on January 15, 2024
    Ajay Andersen is a hacker; not just any hacker; he is the best of the best.

    When left to look after his granddaughters for a few hours, he never expected to end up on the run with them. Nor did he expect to be chased by not only the police, but some people trying to kill him.

    He had not even known he had granddaughters before his daughter rocked up asking for his help, as he had been estranged from her for many years.

    This is a technological, sci-fi story, set in the future. It will grip your interest - or at least it did mine. I absolutely loved this book.
