LotF is a really good book. It drags on a bit at first but it gets really dark/eerie later on. Filled with symbolism/double meanings if you pay close attention to Golding's writing. Have you read it?
Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
