nostr:npub1kt3hutklgrma64ykjwk4trxq9rtyfnxhkjz729g4pd9xl7hzhrjse75004 I'm looking for book recommendations for an 11yo who reads at a much more advanced level. He likes sci-fi. He has read the Hitchhiker's Guide series and loved them. I think he would enjoy some more 'hard' sci-fi as well. He needs something challenging but without subject matter that is too mature. Thanks for any help! #sciencefiction #bookstodon
