Hey, 5E friends, I need some recommendations!

My nephew plays 5E with his friends. They're in like 8th and 9th grade. I pulled his name in our holiday gift-giving lottery and it seems to me like, with your help, I can give him an interesting book or two.

So, if you can, please recommend me:

• 5E books

• In print

• Off the beaten path

• Suitable for 8th & 9th graders

Thank you!
