I'd recommend tje authors Jack London, Joanne Rowling, Rudyard Kipling, Terry Pratchett, Arthur Doyle... in no particular order.

Former (Dutch) teacher here! Diary of a wimpy kid is easy reading for a lot of kids and I always found that the really engrossing books could help them move on to their actual reading level. For my students who liked comic mischief in class, I could always get them hooked to reading with The Saga of Darren Shan.

Don't let the 'horror' genre fool you: the story is dark and funny. Based on the books you named I think your kid might love it!

There is a large selection of Japanese light novels that are being translated into English. This is where a lot of the original source material for anime comes from. The anime is often created to sell the books, in fact.

There's a lot of stuff that won't be appropriate until they hit 13yo or so, but my nephew, a voracious reader, started reading LNs around 10.

Spice & Wolf is a personal favorite that might be a good fit. They will miss out on the romantic subplot but that's only a small part of the story

I'd recommend the Alex Rider series by Anthony Horowitz. It's junior James Bond, my kids loved them.

Me as an adults just gonna be here taking notes for my own reading list , you all are the best for recommending

My boys of that age enjoy the Percy Jackson book series, Harry Potter, and Wings of Fire. We also read them LOTR which they loved, but they haven't reread it themselves yet.

• Unicorn Rescue Society series by Adam Gidwitz
• Ben Yokoyama Cookie Chronicles series by Swanson and Behr
• Wings of Fire series by Tui T. Sutherland
• Wow in the World books by Mindy Thomas and Guy Roz (they have a companion podcast that’s absolutely bonkerballs as well!)

All of these have a nice mix of comedy and mischief/adventure that he might enjoy.

I enjoyed the Redwall series around his age. Yes , they are formulaic after a while, but good fun pulp adventure for kids.

I really enjoyed the TinTin series at that age. Nice adventure stories.

Not sure it fits with what your son like but I think it's around this age my own son started reading the Harry Potter series.

Dog Man, Cat Kid Comic Club, and Captain Underpants by Dav Pilkey. Huge hits among my kids' friends.

The Bad Guys has a movie out, so that's easy to get into.

Our local library had to expand the graphic novel part of the kids section because they're so in demand. Amulet and Bone are really good.

Anything written or illustrated by Reina Telgrmaier (Guts, Smile, Sisters, Ghosts, The Babysitters Club)

I recommend Peter Pan.

Hitchhikers guide to the galaxy.

Gary Paulson's book's are good for that age range. Most of his work is more serious in tone and survivalist (stuck in nature survivalist not doomsday bunker survivalist). Harris and Me is more biographical comedy.

O. Henry was my favorite author at that age, and still something that I revisit. It is written in an older dialect which can be a put off for some people.

That's a good age for mythology. Greek mythology is the easiest to find kid appropriate translations of but Norse mythology is full of daring rogue stories.

The Dangerous Book for Boys is a fun reference book.

Alcatraz Versus The Evil Librarians is exactly what you're looking for! It was written for grades 5-7 and it's chock full of comic mischief, super powers, great morals, and a gripping story. I read it as a young adult and loved the entire series.

Great recommendations from everyone! Just a small add to !parenting@lemmy.world for people interested in a parenting community
