Book recs for 11 yo

[MyFriendsCallMeOh]

Dd1 loves reading but she's grown out of the kids section at our local bookstore and having spent some time looking at the teens section, there seems to be a huge amount of angsty stuff that she's not ready for. Does anyone have any recommendations of books or authors suitable for an advanced 11 yo reader?

My son loves the Mazerunner series, Lord of the Rings, all the Skulduggery books and the Alex Rider series. He's devouring so many books that I am constantly on Amazon (I made the mistake of telling him he could have whatever books he wanted, whenever he wanted, as long as he was reading them, and our Amazon bill has gone through the roof!)

Harry Potter, Judy Blume books, miss peregrines home for peculiar children series, I also loved the point horror books as a kid.
