This is christian fiction, and it's really badly written. This is not christian fiction on the literary and allegorical level of Narnia, it's christian fiction on the literary level of Sweet Valley High, but with less character depth and worse plot placing. I read it because it was free on Nook a few weeks ago, and although I'm not a christian, I found the premise (post-rapture world) to be one that had promise.Unfortunately, rather than write a great book focused on plot and character development with broad appeal, they chose to write a sub-par vehicle for proselytizing. One suspects they intend this book to have broad appeal, and that the horrors they recite (rather than show) will convert non-christians through the power of literature and whatnot. Except the writing is really awful, and it very clearly caters to christian beliefs (and, from what I understand, it's a very specific subset of christian belief).And I don't mean it caters to christian beliefs in the way that a book about the rapture, a book that presupposes heaven and god and all that are real would. It caters to christian beliefs by doing the following:1. Depicts those left behind as suffering from pride, anger, resentment, or rebellion, especially if they already have christian family/ friends.2. Has a lot of preaching and discussion of christian beliefs and accepting Jesus. Most of these religious conversations feel forced and awkward in the settings they're in.3. Propagates a specific evangelical viewpoint that christians are saved by grace, not by works, which is a pretty horrific idea when you think about it from a moral and ethical viewpoint.
