Returning after a long reading break

Hey!

I (25M) have been an avid reader in my teens, but I stopped around five years ago and now pick up way too little books, which I want to change.

My favorite series is Skulduggery Pleasant (which is somehow still going on) and I want to stress that I really adore Derek Landy's writing style.

But I in general enjoyed a lot of Books for Young Adults like Mortal Engines, The Secrets of the Immortal Nicholas Flamel, Lockwood & Co.

Do you have any recommendations for me that fit the vibe of these books? Or maybe something a bit more mature? Looking forwards to your suggestions!
