In addition to fluffy Nora Roberts and not-so-fluffy Diana Gabaldon (we actually had a funny Outlander discussion in my office this morning), I like post-apocalyptic stuff. One of my recent faves was The Passage by Justin Cronin -- a virus turns much of the world into zombie-type creatures, and small outposts of "humans" have to defend themselves. A prequel recently came out, The Twelve, and I haven't gotten that from the hold list at the library yet. Another fascinating p-a series is by Ann Benson -- Thief of Souls, The Plague Tales and A Physician's Tale. They go back and forth between the near-future and the Black Plague period.
