Finished Lucifer's Hammer, it started out slow and boring and kept getting better little by little, until by the end it was extremely engrossing and was put out that it ended when it did. It has nearly everything you can imagine an apocalypse novel would have. Comets, meteors, endless storms, thousands of feet high tsunami waves all over the planet, every fault line on the planet giving off The Big One earthquake, (sounds like Tool's song, "aenima"!) thermonuclear war, imminent ice age...
Am now into Witchhunter, a Warhammer novel. Very very good.
