I like Alanna, but I don't adore her - she's definitely not a favourite character.

There's not much at all, actually! She gets mentioned in the first two (I think she might pop up very briefly in the second), appears a few times in the third, and gets a line or two at the beginning of the fourth but that's about it.

(And now the laptop appears to be dying, so I'm finally off to bed. Night!)
