Awesome zombie romp.
As always a great read that ends too quickly.
You have to read rhe whole series: 1 they are great. 2 this one references a lot of back story. I don't know how he fit it all in: Army Spec ops, Australian spec ops, Seal teams, Dog, John Chase, Russians, Marines, submariners, Naval aviator in a futuristic hypersonic transport aircraft, a 'monster', oh yeah and zombies.
