The first three books in the post-apocalyptic sci-fi series of The Long Night, by Kevin Partner and Mike Kraus, won me over. The next two, “Reapers” and “Betrayed” continue the intelligent, pacy thrills and ideas. In the post-apocalyptic rubble of the United States, the various survivors we encountered in the first three volumes – Solly, his wife, and a small-town policewoman, plus other emerging characters – slowly move towards each other, every step of the way fraught. The stakes have been upped: civil wars erupt across the continent. And the shadowy Lee Corporation, at the heart of the catastrophe releases a new terrifying weapon in its quest for control. A heady brew and a most satisfying read.
