The Runes of War. By Jane Welch, or something like that. Good lord, that was horrible. The plot revolves around how two brothers who have brought up in some kind of Christian-styled religion has to help rescue the missing member of a trio of women who form a Maiden-Mother-Crone trinity of high priestesses in a wiccan-styled religion. Those three together are needed to work the magic that will save the brothers' fortress home from an invading barbarian horde. And of course, in the process of the journey, they have to learn that their male-dominated, polluting society is inherantly corrupt and vastly inferior to the female-dominated, enviromentally friendly society that preceded it.
Ugh.
First of all, I don't get what the big deal is. The barbarians are badly armed and in the process of starving to death. The fortress is described as being powerful enough to shrug off any number of attacks. And magic is so low-key that it's barely even noticeable. Frankly, I'm not convinced that if the defenders of the fortress are so feeble that they can't hold it against a bunch of starving svages armed with knives and clubs, then magic is going to make any difference.
Secondly, while I consider myself an enviromentalist and (reluctantly) a feminist, I hate this kind of propaganda. The notion seems to be that women are natural mothers, and as such are always peaceful and nurturing, and men are natural rapists, and so will ravage the entire universe for their selfish pleasure if left unchecked.
Okay, I admit it. I'm male, therefore biased on the issue. But I still don't think it works like that.
Oh, a token comment here at the end - TV is not inherantly stupid and books are not inherantly smart. I can think of three or four TV shows off hand that I liked better than most books I read. Mind you, TV shows I like (which I will be shamemless enough to claim therefore must be "smart"

) tend to get cancelled a lot, but then, we never get to see all the cleverly written books that never get published, do we?
