They might not realize the legal implications, so I should explain why it's not allowed and provide alternatives. Maybe suggest buying the books through official stores, checking out libraries, or using legal download platforms like Kindle or Audible. Also, maybe mention the TV adaptation in case they're interested in that instead.

I should make sure the tone is helpful and not dismissive. Offer positive alternative options so they feel supported in finding the content the right way. Also, remind them about the importance of respecting authors' rights and the creative process.

Let me structure this step by step: start with a clear statement that what they're asking for is illegal, then explain why, offer legal alternatives, and wrap it up with a friendly message. Make sure to keep it concise and easy to follow.
