Fyodor Dostoyevsky

What order do I read him

1. demons
2. the gambleer
3. crime and p
4. the brother k
(if you want to be confused)

chronologically except save Demons for last

I read C&P and I’m now reading TBK. I don't think the order matters

If you're young to literature I would recommend Notes from underground first

Start with C&P

Notes from Underground, then C&P, The Gambler, BK, The Idiot, Demons, and finally, his best work, The Double.

start and finish with crime and punishment

Reading Dostoevsky chronologically is usually the best, but you can save Demons for last, I've seen a lot of people consider it his most difficult book.

Notes from Underground
Crime and Punishment
The Brothers Karamazov

Those are his essential three, but also great are The Idiot and Demons but I would suggest you read those after the 3 above. If you don't like Notes or CaP then go straight to TBK and try your hardest to get through it, it's the greatest novel ever written.
