DD is a voracious reader, and I'm starting to run out of ideas as to what she can read. She is currently on the fifth book of the Percy Jackson series, but has nothing much lined up after that. She keeps asking me for ideas, but I'm at a loss. Any age-appropriate suggestions would be welcome!!
Her all-time favourite book is Heidi - she has read it umpteen times! Other books/series that she has enjoyed are as follows:
Percy Jackson series
Pseudonymous Bosch series (?something to do with a secret)
Alex Rider series
Narnia
Harry Potter
Lemony Snickett books
Ballet Shoes/white boots/other Noël streatfield books
A Little Princess/The Secret Garden
Pollyanna
The Anne of Green Gables series
Little house on the prairie series
Little women
David walliams books
Enid Blyton stuff (not recently)
Pippi Longstocking/bullerby children
Various Eva Ibbotson stuff
Holes (Louis sachar)
When Hitler stole pink rabbit
The other side of truth (?)
The phantom tollbooth
...and probably loads more that I can't think of.
Books/writers that she hasn't particularly enjoyed for some reason:
Anything by Jacqueline Wilson
Some Michael Morpurgo (she liked Private Peaceful but not others -don't think she has read that many though 
Black Beauty
Mister Monday
I'm running out of ideas. I think she is probably too young for stuff like the Hunger Games or the Divergent Trilogy, but haven't read them, so don't really know. Racking my brains to think back to what I liked as a kid, but she seems to have read most of my old favourites.
Any thoughts?
