Honestly, finding a legal and free version of this novel can be quite challenging. Sometimes, libraries offer digital lending options, but it depends on their collection. It's best to support the author by purchasing the book or using legitimate subscription services.
I'm not sure about a definite place to get it for free. Maybe check out some public domain sites, but the chances of finding this specific novel there are quite low. Remember, respecting copyright is important.
You might try looking on some free ebook websites, but be careful as many of them may be illegal or of poor quality.
