When Jack told me that he and fellow author Ward Larsen had each been selected to write in the Tom Clancy universe, I was over the moon for both of them. I can’t speak for Ward, but I know this was an author dream come true for Jack. The dream is now a reality, with the publication of Pressure Depth.
A writer does not simply walk in to the Ryanverse. One has to be invited, and one has to have demonstrated they have the chops to handle the job. With his own Battle Born series, the Silent Horizons series with Chad Robichaux, and the latest installment in W.E.B. Griffin’s Presidential Agent series, Stewart has shown he clearly has the chops. Now it was time to deliver the next great Jack Ryan Jr. story. And he delivers in spades.
In something of an homage to the book that launched Clancy’s career, Stewart takes us back beneath the waves. Jack Jr. is working a legitimate, “white side” job for his employer, following up on a $150 million insurance claim by a ship’s captain. Jack is to investigate the claim, but in the course of those duties, bumps up against the discovery of an underwater installation, placed by the Soviets during the Cold War. An installation which yields no immediate clue as to its purpose, but given the lengths the USSR went through to conceal it, everyone begins to suspect the worst. Jack Jr.’s employer activates The Campus, the “dark side” of its activities, and the usual cast of characters gets to work.
An F-18 fighter pilot and Topgun graduate in his Navy career, Stewart could write all day on adventures in the sky. (See the aforementioned Battle Born series.) So taking the plot not just underwater, but deep underwater, was a challenge both to his knowledge base and real-world skill set.
That said, Jack does a fantastic job immersing the reader (no pun intended) in the world of underwater operations, from the advanced ROV that discovers the Soviet installation, to the mechanics of saturation diving involving a pressure chamber and a diving bell. Jack doesn’t bog down in the details, though. The technical information is explained in an easy-to-understand manner that helps move the action along. The title of the book is well chosen, as Stewart’s prose makes you feel the pressure of being under water that deep, and the claustrophobic tendencies that come with it.

Stewart has firmly established himself within the Ryanverse with Pressure Depth, to the point of writing the next two Jack Ryan Jr. novels we can expect. This is a thoroughly researched, action-packed thriller worthy of the Tom Clancy lineage, and deserves a spot on the shelves of readers who love these characters.
