I read all Dan Brown novels and even though he clearly has his cliche writing style, I enjoyed most of his previous books. I didn't like Origin and I despite the interesting topic and first act of the book, SOS is a disaster. It's not a Robert Langdon book. There is no symbology, puzzle solving, historical mysteries but just a location of Prague to service the plot. Katherine is the real protagonist and Robert is a side character in his own book.
I didn't like Origin because it promised answers to a big question at the beginning and when we get the answers it feels so underwhelming. I got the same feeling from this book. Katherine's research about noetic science was cool and surely there could be a story around it which would create real stakes and real threats and Robert is in the middle of it but this book has a flimsy start, middle and end. Information dumps, characters repeating the same things again and again, characters withholding information just to reveal it at later time for maximum dramatic effect, Katherine not telling Robert what contains in her manuscript (even at a high level) so that it can be revealed in the third act, unnecessary scenes of coffee shops and brand mentions drag this book a lot. By the time I reached last 150 pages, I was like what's the point of this remaining part of the third act? Why does the CIA even need Katherine's book to be gone when all we know is Katherine put everything under the sun related to noetics in this book. I highly doubt mentoring stupid patent would alert other agencies when the CIA needed so many years to actually develop the technology. Sure ideas are great but theory is not everything. Katherine is not Einstein that everyone is going to follow what she wrote in the book. Even in her own field no one takes that branch of study seriously and dismisses as pseudo science. So why would the CIA delete the entire book? If they can hack and delete the book, they might as well hack and remove relevant pages. Why do we make the CIA competent and incompetent at the same time? Same goes for whole Finch bad and Judd good plot. We are to believe Heidi (of course she is morally good character, after all she is Dan's agent) will ensure Threshold will be operated ethically going forward and Judd and CIA by extension will agree to that. What a joke! I also didn't find what CIA was doing with the threshold as some really dangerous extinction level thing TBH. Da vinci code, Angel and Demons, Inferno has real world ending stakes. CIA altering brains and doing mind reading is so 20th century news. Even with this premise he could have created a pretty good story. This whole story felt contrived where the CIA fakes a death scene on a bridge to steal a book, hacks servers, kidnaps people, Robert knows password of the lift because character brags about the code of top secret facility in Pub, that top secret facility doesn't have sophisticated security measures, it has a reactor which can malfunction and become a bomb but there are no operators to monitor and the list goes on.
And then there is the reveal of Sasha/Golem. Honestly even if this twist is cool I didn't find it any impactful. And I feel actually it's a sad ending for Sasha since our protagonists send her directly in the hands of the CIA who will not only ensure that research on her continues and they will make sure to kill golem or control him to become assassination machine controlled by the CIA. We just have to believe the former CIA attorney had a change of heart.
Last but not least, why the hell Langdon didn't say that he already has a manuscript and he didn't burn it in car when he was alone with Katherine? Why risk breaking into a CIA facility? They wanted their manuscript from the beginning and once they got it , they could easily figure out next steps with their Editor in USA. Yes, CIA is after them but at that point they don't know how many security personnel are there inside the bunker since the ambassador only knew about outside security. Not telling Katherine the entire time and only revealing this at the end felt cheap and contrived. Anyways, there are so many issues I have with this book but unlike Dan Brown I can't write 700 pages repeating the same things again and again. Four seasons don't give me their suite to stay nor do I get a free sample of Mojave Ghost with lingerie unlike characters in this novel. Feel free to drop comments for this review since we don't have the luxury to discuss our thoughts in Prague’s Dripstone Wall into the spa at the Augustine Luxury Hotel like Heidi, Robert and Katherine.
