I’ve spent way too much time hunting down free reads online, and 'Rome' novels are tricky because the title’s pretty generic. If you mean historical fiction like Robert Harris’ 'Imperium', Project Gutenberg’s a goldmine for older classics—think 'Ben-Hur' or 'Quo Vadis'. For newer stuff, check out Open Library; they sometimes have borrowable digital copies.
Just a heads-up, though: a lot of 'free' sites are sketchy. I’d stick to legit platforms like Libby with a library card. If you’re into fan translations or niche works, Scribd’s free trial might help, but always double-check copyrights. Nothing kills the vibe like malware popping up mid-gladiator battle.
