Any good books for 9yo advanced reader?

[onthewarpath]

My DD1 is in year 5. Yesterday we had parents evening and we were told she has an 11yo+ reading comprehention and fluency. My problem is I do not want her to read bookd adressed to teenagers with issues I do not want her confronted with yet. But, would like to find something chalenging enough for her. She has read classics like "the secret garden" but did not enjoy it so much. She has finished all the Roald Dahls we had and is now reading a collection of Paddington bear books. I have nothing to offer her after that so any suggestions would be great. I was thinking maybe the Harry Potters book could be good? Anyone with children who have read them and could give honest opinion non commercially based?

Lemony Snicket (whole series) starts with Bad Beginning
Angie Sage. Araminta Spook
Enid Blyton. St Clare Stories, or Malory Towers(school stories)
Roman Mysteries (can't remember author)sometimes a bit realistic but exciting adventures about life in Ancient Rome. Girl heroine.
All Harry Potter. You will enjoy too.
Laura Ingalls Wilder. (life in log cabin)Little House in Big Woods (some children don't like this but I loved it)
Astrid Lindgren. Pippi Longstocking.
Narnia. starting with Magician's Nephew by CS
Lewis.
Anne Fine. Bill's New Frock. My 8-9 year old found this hilarious.

A few suggestions.
Secret Garden etc can be bettter read aloud?
And A Little Princess by same author was my favourite.

My DD 11 yr6 has been bought up with the films has only started reading HP about 2 or 3 weeks ago and has read all of them and become slightly obsessed at the moment.
They were written for 10 plus and the characters age with the books so obviously start to cover more teenage themes eg first kisses and jealousy but nothing like drugs etc. From the third one onwards they do become a bit darker.
DS 13 has also read them as they have been released.They were the only non fiction he would read until a few months back.

dd1 age 8 read the harry potters last year (except the last one which she decided was a bit grown up half way through.) and really enjoyed them. she's rereading them now, so i suppose i ought to think of some new books for her lol.
she does like the whole malory towers type, and i'm not particularly bothered by the content, but some folk think they are too dated...

Noel Streatfield?
Rummer Godden?

dd1 is the same age and reading age. She's not that enthusiastic about reading but has enjoyed the Roman Mysteries, a couple of the less teenagy Jacqueline Wilsons, Ballet Shoes and a couple of other Noel Streatfields. She also loves some book of girls stories that she had as a birthday present

thanks swanriver, DD1 also read "A little princess". she is now reading an Enid Blyton book from school, I cannot remember the tittle, pretty sure there is a parrot on the cover, will check tonight. I will try to make her lean towards the Laura Ingals ones as I was watching the series when a little girl myself and loved it, this way I can pinch it from her when she is asleep...
Thanks lostgirl I have not heard of Noel Streatfield and Rummer Godden (am from the continent and am more into French litterature) but will google them as they have been advised by several people.

Well thanks everybody really as all suggestions seem appropriate. thanks for the comments about HP.
