Wait, I should confirm if this book is actually available. If it's obscure, maybe it's not available legally, but the user might not know. Still, the main point is to steer them away from pirated copies and towards legitimate sources. Also, check if the PDF repack is a real thing or if this is a scam. If I can't find official info, that adds to the risk. Make sure the user is aware that they need to take responsibility for their actions.
