I realize that it's a fantasy series, but I want the science in some ways to be at least marginally believable. There are a few things in here that are a bit too far fetched even for a fantasy series. Maybe I'm old and getting a little crusty. Maybe I should shut up and just enjoy it for what it is. I'll wait a few weeks before going into some of these points in detail, but I'm curious to see if others pick up on some of these things as well.
