If it’s not a famous book, you may find some Goodreads reviews and if you’re lucky a Reddit post or two, but not vasts amount of online discussion like you’ll find about any passingly good series or movie.
And if you love a movie or a tv show, it is much easier to convince people in real life to also watch it, since it’s way less time consuming and not everyone even reads books, but most people watch movies.
I just think that this really sucks about reading books.
Audiobooks are great for multiple people experiencing a book together.
It’s not a situation you’re going to find yourself in a lot, but if you have a friends or family that might enjoy it, consider putting aside sometime to share the experience of a book together. Consider it binging a show, maybe on a road trip or something, once a week you set aside an hour together. It’s a really unique experience that not many people have had to share a book.
Audiobooks are often considered by muggles to not count as reading, but the ironic fact is that they actually let you do more than you could with a regular book. Can’t wash dishes or drive cross country reading a paper book, and as I stated already you can’t share the experience with 20 other people in the same room with paper.
