I appreciate your help, everyone. I don't have a ton of time for reading, and I read rather slowly anyway, but I'll probably go with at least one of the titles you've recommended for evolution. (The Origin of Species is very slow going for me, and will probably take me at least a month to finish).
I'm suprised there aren't more books that cast doubt on the theory. I don't care if they are labeled Intelligent Design, or Creationism, or whatever. In fact better would be a books by mainstream scientists that have trouble with evolution. I'm getting the idea that these don't exist, and there really aren't any arguments against evolution that the scientific community finds problematic.
In the end, if I don't find anything to disprove evolution, I will still have faith in the Lord. I trust science a lot of the time, in most cases. But I always trust in God.
