My DD (7) is a big reader and with lots of time on our hands in lockdown we're beginning to exhaust our book supply. I'm therefore looking for book suggestions. I tend to go back to ones I read as a child when recommending (Enid Blyton, C.S.Lewis etc) but am aware there's a whole world of more modern books out there.
For context, she's read the Harry Potter series, Narnia series, Michael Morpurgo collection, Heartland, Famous Five etc. As you can probably tell, she is a bit of a serious soul so suggestions please. Thanks in advance
