Don't worry, Fionn. I'm told that it is a natural part of cognetive development to want to read something "just like that one I just enjoyed", so she's probably right on schedule. Think of them as cerebral fiber. Nutritionally necessary, with no vitamins. (for a real hoot, read some of the earlier editions; they get updated periodically, so she no longer wears a cloche or drives a roadster with running boards.)
