There are a few websites that might host free light novels. But be cautious as many of them may operate without proper authorization. One option could be to check fan - made translation communities. Sometimes they share free versions within the boundaries of legality. For example, if the original work is already in the public domain in certain regions, it might be available freely through these channels. But always respect the rights of the authors and publishers.
Honestly, while it's tempting to look for free versions, the best and most ethical way is to support the official release. Buying the light novel not only ensures that you are getting a high - quality, legal copy but also supports the creators. If you can't afford it, you could wait for sales or promotions on official e - book platforms.
You can try some free e - book platforms. However, make sure they are legal. Some libraries also offer digital lending services where you might be able to access it for free legally.
