Books for 12 year old similar to Percy Jackson or Keepers of the Lost Cities

[LilyLemonade]

As the subject states I'm looking for recommendations for books for a 12 year old girl who has loved these two series. Many thanks!

There's a series following the Percy Jackson books by Rick Riordan called the Heroes off Olympus series which my 10yo has loved.

All Rick Riordan books are great.
Maybe Artemis Fowl series? Scarlet Thomas’ Worldquake series? Strangeworld series by L.D.Lapinski?

Thank you!

I've not read the ones mentioned in the title but when I was 12 I'd loved the Mortal Engines series and the prequel series Fever Crumb by Philip Reeve.
