This is bad advice. Theft is never justified. Stealing is stealing. I feel bad that this person can't read the books they would like to read, but that doesn't give them the right to steal from the author.

OP, I suggest you find other books that your parents are willing to buy or look into books that are downloadable LEGALLY and freely. Many authors offer some of their books for free. Many classics are public domain and free to download through various sources.

But do not encourage pirates by using their websites. This is wrong!
