I will recommend this book as a strong candidate to add to your collection. It is elements of a traditional litrpg without any connection to an earth reality at all. It’s simply a world where abilities are given when people come of age. There are some confusing aspects of world building and limitations that don’t quite make sense but I’m prone to over analyzing and it may become clearer in future books.
The narrator was great as expected an I’m looking forward to future installments in the series!
