Ah, 'The Possessed' (or 'Demons' in some translations) by Dostoevsky is such a gripping read—full of psychological depth and chaotic energy. If you're looking to dive into it online for free, there are a few options, though they come with some caveats. Project Gutenberg and other public domain sites sometimes host classics like this, but translations can vary in quality. I'd recommend checking there first, as older translations might be available legally. Just keep in mind that the language might feel a bit dated compared to modern editions.
Another route is libraries with digital lending services, like OverDrive or Libby. You might need a library card, but they often have free access to e-books, including classics. I’ve found this super handy for catching up on older titles without spending a dime. If you’re okay with audiobooks, platforms like Librivox offer free, volunteer-read versions—perfect for listening while you’re multitasking. Either way, it’s worth poking around to see what fits your reading style best. Dostoevsky’s dense prose can be a lot, so having a format you enjoy makes all the difference!
