No you do not have to read anything prior to reading The Secret History, it does not spoil any of the texts you mention. It’s more like nods to them which make you go “noice, I see what Tartt did there” if you’ve read them but the book can very much be enjoyed on its own.

At the risk of being downvoted into oblivion, Gravity’s Rainbow by Thomas Pynchon. It made me feel ill how pointlessly disgusting it read to me. Close seconds: Child of God by Cormac McCarthy, Black, Leopard Red Wolf by Marlon James. Give me something to forget please. 😭

May she rest in peace.

Thanks for the insightful review.

I agree with your assessment OP. It was fine but quite underwhelming overall.
