I think you’re in the correct subreddit, there’s often queries about English-language books from non-native speakers.
As for those two, I’ve read American Psycho and it doesn’t have too difficult a vocabulary for a non-native speaker. However, there are a few sections where the character is high on/coming down from drugs and can ramble incoherently. But these don’t take away from the enjoyment and comprehension of the story I feel.
