While it does invoke certain supernatural elements I would disagree that this makes them less rational. Angels exist, but are fallible, mortal and material creatures composed of Dust. Dust itself is a fundamental particle with known and predictable behaviors, though admittedly ones that are somewhat implausible. The biggest leap is the world of the dead in the final book, but I found it a very good description of how awful an afterlife would actually be, and the problems with an all powerful god figure.
In terms of rationalist virtues, the children succeed by being self reliant and intelligent, and it avoids the heavy handed morality of most YA fiction (for example the main character is a skilled liar, and thats seen as a good thing when used well).
It kind of goes in the opposite direction, to the point where I find it jarring. "The boy is a murderer." "Oh, that means I should trust him." Buh?

For good or ill, we seem to agree that fiction strongly influences the way we grow up, and the people we come to be.
So for those of us with the tremendous task of bringing new sentience into the world, it seems sensible to spend some time thinking about what fictions our charges will be exposed to.
The natural counter-part to this question is, of course, are there any particular fictions, or types of fiction, to which we should avoid exposing our children?
Again, this is a pattern we see more commonly in the religious community -- and the rest of us tend to look on and laugh at the prudery on display. Still, the general idea doesn't seem to be something we can reject out of hand. So far as we can tell, all (currently existing) minds are vulnerable to being hacked, young minds more than others. If we determine that a particular piece of fiction, or a particular kind of fiction, tends to reliably and destructively hack vulnerable minds, that seems a disproportionate consequence for pulling the wrong book off the shelf.
So, what books, what films, what stories would you say affected your childhood for the better? What stories do you wish you had encountered earlier? If there are any members of the Bardic Conspiracy present, what sorts of stories should we start telling? Finally, what stories (if any) should young minds not encounter until they have developed some additional robustness?
ETA: If there are particular stories which you think the (adult) members of the community would benefit from, please feel free to share these as well.
ETA2: My wildly optimistic best-case scenario for this post would be someone actually writing a rationalist children's story in the comments thread.
