I'd suggest The Plague by Camus and Animal Dreams by Kingsolver in place of what you've selected. I haven't read The Fall, but I really liked The Plague. I preferred Animal Dreams over Poisonwood BIble.

If there were one book I'd suggest for your next I would say one of the two by the author Orhan Pamuk: My Name is Red (my favorite) or Snow (more critically-acclaimed and still excellent).

Blindness by Jose Saramago is good for the apocalyptic bent

An easy and funny read is The Santa Land Diaries (I think) by David Sedaris. It's a collection of humorous essays.

Some interesting non-fiction: The Botany of Desire by Michael Pollan.
