you could do dystopian texts like 1984, but if you do try not to do the generic related ones everyone else does (fahrenheit 451, brave new world, catch 22, etc). i did 1984 in y8/9 and if you're choosing dystopian i would rather recommend 'we' by yevgeny zamyatin (it was written before orwell and was actually an inspiration for 1984), i thought it was interesting
i honestly think you could also do kafka's stories (trial or the metamorphosis) as related texts. another one that could be good that i really liked was 'do androids dream of electric sheep' (it's short?? i think?? in the sense it took me 2 days to finish it?? but a scifi)
