After the massive cliffhanger at the end of Starbound, our heroes are stuck on Earth. The Others have stopped all electrics and electronics from functioning. Civilization is collapsing and things are generally looking grim.
Compared to the previous two volumes, the concluding book is nowhere near as good. The premise is clever and intriguing, but it devolves quickly into a story about how to survive the end of civilization. The epic storyline dealing with the Others and what place humanity will have in relation to them, which has been the main thrust of the plot in the first two books, is almost completely ignored. Spy makes a couple of appearances, but what they mean is never explained. Much of the story seems rather random. The monumental deux ex machina at the end is simply adding insult to injury. If you’ve read the first two books, by all means read on to find out what happens with Carmen in the end, but also be thankful the book is short.
