5 stars out of 5
I suppose it sounds strange to give a book a 5-star rating when there were chunks of it I totally skimmed, but let me explain. Once when I visited a top-of-the-water submarine in downtown Cleveland and had the chance to venture down the tube that led to the guts of the beast, I took one look and ran the other way. Yep, I’m definitely on the claustrophobic side, so being seriously enclosed like that, even if it’s not under water, is pretty terrifying. Well, guess what this book is all about?
Mind you, I wasn’t too fearful that the hero of the story, Jack Ryan Jr., son of U.S. President Jack Ryan (he of The Hunt for Red October, an all-time favorite book), would meet a watery, highly pressurized demise. But over the series, I’ve come to know and love several of his friends and cohorts at Hendley Associates, where he fills roles on both the “legitimate” and clandestine sides of the company, so I was worried about them. And as can be deduced by my earlier comments, I can’t think of a worse way to go than on the sea floor mere feet from the Mariana Trench – the deepest oceanic trench on Earth.
This time out, Jack – whose fiancĂ© and co-worker Lisanne Robertson are no longer an item – is planning a dive with co-worker Doug Park to inspect a sunken ship in the Philippine Sea near Guam thought to be carrying illicit and potentially dangerous cargo. Meantime, on another ship, captain Carla Bennett has spotted an object dangerously near the Mariana Trench that shouldn’t be there – it appears to be about the length of a submarine and has a corroded hull. More importantly, perhaps, is that it has a logo that looks suspiciously Russian. So what is it and how did it get where it is now? Further research finds it just may be one thought to have been surreptitiously placed by the Russians long ago for nefarious purposes. To get to the truth, Jack and his dive team will need to sink to all new levels. Problem is, someone else is determined to get there before they do and stop them from learning the truth.
For sure, it’s a mission fraught with danger - the details of which, of course, will be revealed as the story unfolds (I’m certainly not doing to be a wet blanket and spill the beans). I will say, though, that I learned way more than I ever wanted to about deep sea diving (a lot of it so technical it went way over my head, actually). And if I weren’t already certain I’d never want any part of deep sea diving, trust me, I’d be convinced after finishing the book. Parts, in fact, I had to skim over or else face having nightmares for weeks to come.
All that said, though, it’s a riveting, well-written story – and I’m already looking forward to the next adventure (though I’m hoping most of it will take place on dry land). Meantime, I thank the publisher, via NetGalley, for the opportunity to read and review a pre-release copy of this one.
