Book reccomendations for young boys

[MaximoMark]

Hello,
DS is in Year 2 and since Xmas has properly cracked reading and is now quite the bookworm!

He got assessed in school this week as having a reading age of 9.5 - any suggestions for books to read?

He’s read a few of the horrid Henry’s but not that much of a fan (and nor am i), most of the roald dahl’s and a couple of dragon based books.

He’s fairly soft and so doesn’t like any sort of danger, I considered the famous five but I think he’d freak out.

We’re going on holiday soon so would be good to take him to the library and guide him to some good suggestions.

Thanks 🙏

Also the Dragons Realm set of books by Katie Tsang

The Tree House series

ds (8) is an advanced reader skill wise (11/12 year old equivalent) but is a reluctant reader so if he shows any interest in a book series I will buy him all of them.
his current favourite is the ‘dogman’ series- on first glance it looks very easy reading, but it does have some harder vocab and concepts than it appears on the surface. He just finds them hilarious and happily reads them without any cajoling from me.
he also has recently enjoyed ‘the worlds worst monsters’ book by David walliams, ‘dirty beasts’ and ‘revolting rhymes’ by Road Dahl
