Cold Burn: A National Parks Thriller

By A. J. Landau, Jeff Ayers and Jon Land

Agent Michael Walker returns when multiple deaths at Glacier Bay National Park are just the first steps in a potential global disaster. National Park Service investigator Michael Walker is battling smugglers stealing priceless artifacts when he’s dispatched to Glacier Bay National Park in Alaska, where, in the first stage of a potential global disaster, a team of scientists has gone missing. Meanwhile, in Florida’s Everglades National Park, FBI special investigator Gina Delgado traces the murder of an environmental science intern back to another U.S. Geological Survey team’s ongoing experiments that are decimating the fragile ecosystem. That is before she’s dispatched to the scene of a sunken U.S. nuclear submarine, the entire crew of which has inexplicably been killed. The connection between these disparate investigations lies in a deadly prehistoric organism, frozen for thousands of years in the ice until global warming brings it back to life in what could mean the death of all life on Earth. An organism that a rogue billionaire sees as the ultimate fuel source and a Russian strongman views as the ultimate weapon that can shift the global balance of power forever. Against that backdrop, Walker and Delgado find themselves desperately doing battle across multiple fronts against an ancient, unstoppable enemy.

I discovered this series last year and enjoyed it very much, where the storylines are centered around crimes in National Parks across the country. Michael Walker, Special Agent of ISB, which is kind of like the FBI for the National Park Services, and Gina Delgado, Special Agent of the actual FBI, are both back, and initially, are investigating two different crimes: one in the Florida everglades and the other in the Alaskan territory of the native Tlingits, who are very distrustful of outsiders, especially any government representative. There is another storyline of retrieving the bodies of the crew members of a sunken submarine. Needless to say, there is a lot going on here.

The book summary is pretty vague and just basically introduces the three different storylines. As Michael and Gina begin their separate investigations, it’s not long before it’s revealed that climate change is at the center of both of their cases. Shortly thereafter, Gina is assigned to the investigation of the deaths of the crew of the sunken submarine and is off to AK. It’s there that she catches up with Michael, and the two of them realize that all their cases and the deaths of the sub crew are all connected.

It’s well into the second half that Michael and Gina realize that an event that is the result of climate change is the connection between all three of the incidents. There are scores of frozen fish washed ashore, a defrosted wooly mammoth and the plight of the crew members of the sunken submarine, add in a dreaded Russian sub in the area and scores of Russian hitmen stalking a glacier near the Tlingits village, and you have a really interesting story depicting the dangers of climate change as well as the extent that greed and corruption has infected a few people in power.

The continuing character development of Michael and Gina was good to see. The pacing was steady to fast and never seemed to drag, at least not for me. I enjoyed all the passages about how climate change affected the way of life for both mammals and sea creatures. The writing was well done and, once again, enjoyed the educational passages as well. Don't know if the info provided is accurate but it seems feasible. I’m looking at an overall rating of 4.3 that I will be rounding down to a 4star review. I want to thank NetGalley, St Martin’s Press for sending me this eARC in exchange for my honest review.
