I really like Jacqueline Wilson, though I am aware this may change when my dd is old enough to read them and starts to treat Tracy (severely damaged) Beaker as a role model.
I love the 'unreliable narrator' aspect of Wilson - the way it is all uncompromisingly the child's version of events but you read between the lines about what really happened (eg the way Tracy believes her mum is a famous actress, or that it's never her fault when she gets kicked out of foster homes).
Or 'The Bed & Breakfast Star' when she is constantly telling bad jokes and you can just see how irritating that must be for all around her?
I think Turquoise has it about right - the emotional drama queeny side of girls. They love the high emotion.
I was always reading about orphans at that age, but mine were usually Victorian and lived in orphanages or had evil governesses. Same difference, really.
I do agree about Clarice Bean though - brilliant.
