This is a Will Jaeger thriller, in which he battles to prevent the release of a deadly toxin that threatens global calamity, as well as continuing a long search to find his kidnapped wife and son. I haven’t read the first book in this series (Ghost Flight), but the story held together pretty well all the same.
The book had some exciting passages and was an enjoyable read, particularly the battles in the depths of the jungle and the heroics of Jaeger and his team – all areas where Grylls brings his expertise from the SAS to bear. Unfortunately, the climax to the story fell pretty flat for me. On the one hand, I’m willing to believe that a handful of special forces operatives can win a gun fight against a small army of mercenaries (!). On the other, I can’t believe that a source of immunity against a plague can be isolated from a blood specimen, turned into a vaccine, and mass-produced at world scale in just a small number of days/weeks. That incredible feat of bio-engineering certainly deserves more than seven lines in the epilogue (and that’s in a large font)!
