For the most part, Damon Lindelof's "The Leftovers" has followed very closely Tom Perrotta's "The Leftovers". Tiny tweaks have been made here and there to make the story more cinematic and set it up for a longer life, but the main plot points remained in tact. That was until the tv series hit episode eight, "Cairo".
Book comparisons, and what the deviations could mean for the future of the show after the break. Book spoilers, obviously.
