This is John Ringo's fourth, and final, foray into the world of the zombie apocalypse. I believe that I felt that the second volume held promise of a Lockean reconstruction of civil society. Well, we do get civil society back, and it is more or less Lockean, but there's not much political or philosophical discussion here.
Wolf Squadron has been split up with one part operating in the Pacific, specifically around San Diego and the Coronado Naval Base. The other part continues operating along the Atlantic coast of the US. The first objective is Blount Island near Jacksonville. This is the Marine Corps Blount Island Command, which oversees the Maritime Prepositioning Ships (MPS). As such it is a valuable store for ammunition, weapons, and other supplies. The action on and around the island occupies about the first third of the book.
One of the highlights of this section of the book is when Faith gets to drive her first motorized vehicle. If you know Faith, you know it's not an ordinary car.
Wolf Squadron moves up the East Coast clearing out zombies, and makes it to Washington, DC. Everything has been going fine politically up to this time. The nominal head of the US is someone who was about number 150 or so on the succession list. Unfortunately they rescue the Secretary of Education, an idiot who manages to make Jen Psaki and Marie Harf look like geniuses. Faith goes on a last minute quest to find a higher ranking person of intelligence to replace SoEd bimbo.
Overall it's up to Ringo's usual standard, and the people that we've come to love, Faith, Sophia, and the rest, are all there.
Next up, Finnegans Wake.
