@luckyduck It's def not epic -- more magical realist in subject and style. For expansive epics I might recommend... Dhalgren, or The Bully of Order, or reading a whole pile of Louise Erdrich in chronological order, or Isabel Allende, or Salman Rushdie, or maybe Station Eleven (which is fantastic, but not vast) or The Country of Ice Cream Star, or A Constellation of Vital Phenomena. Or probably just about anything by Richard Powers.
@luckyduck However that said, my list is largely not made up of doorstops! Dhalgren and some of Richard Powers' novels are probably the only ones that'd break a bone if you dropped 'em on your foot.
