"The smart girl sits among the boys whom there is no book in front of."

Translation: Az okos lány azok közé a fiúk közé ül, akik előtt nincs könyv.

another suggested translation started with "azok köze a fiúk köze... I had "a köze a fiúk köze.. which was rejected. Why do we need "azok" here?

[vvsey]

Because it is "azok a fiúk", in plural.
If it were just one boy, "az a fiú", you could say "a mellé a fiú mellé". Or "az elé a fiú elé".
