Whiteout was one of the scariest books I have read in a long time. It might seem slow and boring to begin with but believe me that is just so you have time to totally relax before the nonstop action. It was scary because of the unbelievable dangerous conditions of Antarctica in the wintertime and because of the mission impossible scenarios Rachel went through to try and survive. And it was scary because it was way too believable that all the scenarios presented in the book: a nuclear attack, what was happening because of climate change, and politicians and greedy oil barons disregarding what drilling for oil would do to the earth, could really happen in the not-too-distant future.
