This is why I said it was an essentially useless description, and really only meant it as a joke. You can say something is "like" something else, but in what specific way? I'm currently reading John Wright's Orphans of Chaos and there's a quote on the cover comparing it to the Narnia books. So far, I don't find it anything like Narnia at all, apart from a few superficial details. But apparently that reviewer thought otherwise.

I'm really not a big fan of the Covenant books either; but they were the first thing I thought of to describe my hero's skepticism in the face of the fantastical.
