The Arsenal spins right out of the double-length special Mid-Wake, and we deal with the fallout of Karamatsov's death while the rogue Chinese threat looms. We're also introduced to a surviving Nazi element from earlier in the series; adding more dynamics to this new political landscape.
If you were expecting a breather after Mid-Wake, you won't get it. This novel opens up with an assassination attempt against John Rouke that sends his family off in different directions as they attempt to end the Russian communists while simultaneously dealing with a potentially hostile Chinese faction in possession of nukes. Ahern's writing remains the same; a bit repetitive but descriptive enough to enjoy. The characters are developing well, with a regression for Natalia which is completely understandable given her actions in the previous book.
There's plenty of action, twists, and survivalist situations to be had so continue on with the series if you've been liking it so far. The Arsenal gets a solid 3/5 stars and 4/5 for post-apocalyptic pulp fans.
