Was it the “leaked” version of the Half Blood Prince? If so, a girl I was interested in sent that to me saying that her aunts friend worked for the publisher and I couldn’t show anyone or else they’d all go to jail. I was in high school so of course my mom was suspicious when I was spending hours reading something on the computer, so she made me tell her what it was, and I remember crying and begging her not to tell anyone that this girl I wanted to bang had sent it to me haha
