No, we just have the one daughter. But I was a boy, and I loved reading too. I don't remember needing books to mirror my experience, in fact I probably preferred books which didn't since I mostly found my own experience fairly boring!

Some recent-ish off-the-beaten track suggestions that our daughter really liked that might be appealing to boys:

1. The Unknown Adventurer books (https://www.theunknownadventurer.com): beautifully illustrated, Journey to the Last River is wonderful. We have the Lost Book of Adventure too, but our daughter didn't enjoy that one as much, I think that one would appeal more to boys. Looking at the page I see they have a third, I'll have to pick that up.

2. Almost anything by David Almond, although his young adult stuff tends to blend into his adult work and not all of it is appropriate/interesting depending on reading/maturity level. Plenty of male protagonists, mostly universal themes, some quite strange. I'd recommend reading them first to get an idea if they'd be good for your kid, I loved them. His first book Skellig is probably a good place to start just to see if you like the style or not, although they're all quite different from each other.

3. We really liked A Wish in the Dark, by Christina Soontornvat. Some social commentary but also a great story in an interesting world: https://soontornvat.com/books/a-wish-in-the-dark/. I also highly highly recommend All Thirteen, the non-fiction story of the Thai cave rescue, absolutely amazing story: https://soontornvat.com/books/all-thirteen/.

4. The Orphans of the Tide series by Struan Murray are great adventure/fantasy stories, if occasionally a little dark for younger kids. We got distracted before getting to the last one in the series, but the first two were good.

I can't help so much with stories specifically for boys, but generally I find that just focusing on high-quality, well written books of any stripe are a good bet. If you have a good bookshop nearby, go and find the helpful person - they can help steer you. And buy books from them so they stick around :-)
