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.
I dont care, really. A lot of times Goodreads are just not fair at all. I read a book „Saha“ by Cho Nam-Joo this year, its good, but it barely hits 2.7 stars there. Or Jonathan Carroll, my favourite author of all time. And Goodreads cant event recommend me any book similar to his… But I think, u just read and enjoy it. Create a journal, write some thoughts down, create ur owns little worlds. Reading is ur personal experience created just for u.
