Some major writers have a huge impact, like Ayn Rand, who to my mind is a lousy fiction writer because her writing has no compassion and virtually no humor. She has a philosophical and economical message that she is passing off as fiction, but it really isn't fiction at all.
Huge impact Quotes
I was very influenced by The Magic Mountain. It's a book that had a huge impact on me. I loved that as a shape for a novel: put a bunch of people in a beautiful place, give them all tuberculosis, make them all stay in a fur sleeping bag for several years and see what happens.
