"Books can be divisive because of their styles, controversial subjects, or for just not meeting readers' expectations. Reviews for hyped books are often overwhelmingly positive at first, leading to disappointment. What makes any book, particularly a science fiction book, polarizing? Controversy is certainly one way to define a polarizing book. In the current political climate, so many people are trying to ban books, which is keeping controversial books in the public conversation.
For me, the core of what makes a polarizing science fiction book is the love-or-hate relationship that people have with it. If people have dramatically opposing views of a book, that's pretty polarized. In a genre like science fiction, so often rife with social commentary, the list of polarizing books is pretty long." ~Book Riot
