I've found that no one complains about pop culture being a source of someone lecturing to them. If someone's telling you about Kim Kardashian, you're not going to accuse them of lecturing to you. If I can explore an intersection between pop culture and science literacy, then it generally will not come across as a lecture.
If you truly love a book, you should sleep with it, write in it, read aloud from it, and fill its pages with muffin crumbs.
