The internet is a treasure trove for free English novels if you know where to look! My go-to spots are Project Gutenberg and Open Library—they've got thousands of classics like 'Pride and Prejudice' and 'Moby Dick,' all legal and free because they're in the public domain. I love how easy it is to download EPUBs or read directly on their sites. For newer titles, ManyBooks aggregates freebies from various sources, and sometimes you stumble upon hidden gems.
If you're into fan translations or web novels, sites like Wattpad and Royal Road are buzzing with amateur writers sharing original stories. The quality varies wildly, but I've found some real page-turners there. Just be prepared to sift through a lot of rough drafts! Librivox is another cool option if you prefer audiobooks—volunteers narrate public domain books, and it's perfect for multitasking.
