I love digging into books online, especially when I can find hidden gems without spending a dime. From what I've seen, 'The Endless Night' isn't widely available for free legally. Most platforms like Amazon or Google Books require a purchase, and free copies floating around are usually pirated, which I avoid because it hurts authors. Sometimes libraries offer digital loans through apps like Libby or OverDrive, so checking there might be your best bet. If you're into similar dark, atmospheric reads, 'House of Leaves' by Mark Z. Danielewski occasionally pops up in free trials or promotions. Always support creators when you can!
