How does this series compare to other books in terms of thematic level/suitability? My DD has read (amongst other things):
Northern Lights trilogy
Harry Potter
Tiffany Aching (although 4th put her off 5th)
A monster calls
Everything Rich Riordan has written
She really enjoyed Northern Lights and wants to read the Sally Lockhart books, but our local bookshop has them in the teenage section and I am not sure why.
Thanks!
