Allan W. Eckert, The HAB Theory, orig. Pub around 1976, now from iUniverse, Author’s Guild Backinprint Edition, ISBN 059500820-8, 2000, 500 pgs, paper, reprint. HAB is the acronym for the character "Herbert Allen Boardman." This thriller supposes that the world can come an end because of a sudden pole shift. There is a lot of intrigue and violence along the way as people try to unweil and hide the secret (sort of like Dan Brown’s Da Vinci Code). Toward the end, the president of the United States has to take very authoritarian measures to keep some sort of legacy for a future reborn civilization. The lights do go out. In its day this was a very effective thriller.

Larry Niven and Jerry Pournelle. Lucifer's Hammer orig. 1982; Random House Mass Marketing Paperback, ISBN 0449208133; there have been multiple editions with each author’s name. Here the Hamner-Brown comet strikes the earth about a third the way through the book. The strike bifurcates the story into before and after, and the book describes what it would be like for civilization to recover. Much of the story happens in the California San Joaquin Valley. Ironically, a main character Harvey Randall is a filmmaker. There is a harrowing scene where a diabetic hikes alone through the cold Sierra mountains after the strike; there is massive flooding and damage to nuclear power plants. The book looks forward to the movies 'Armageddon' (1998), about an asteroid, and 'Deep Impact', 1998, about a comet; both films at this link.
