That's what I was going to say. A teacher read Lamb to the Slaughter when I was in about year six. Excellence.Roald Dahl?
I liked Dubliners too. Look into The Complete Short Stories of Ernest Hemingway.Just read Dubliners (albeit for HSC) and I really liked it.
Read Roald Dahl as a kid but interested in something a little more sophisticated...
\In terms of writing style, I think Kafka and Nabokov has some really beautiful writings which can get slightly tiring in a novel. Hence why they are better suited for short stories. Try.
If you enjoyed Roald Dahl, you'd probably enjoy Lewis Carroll as well.
