I suppose this is something that may inevitably happen to every reader. You love everything a certain author publishes and then suddenly, there is a book that you just don’t click with. So, what do you do? It doesn’t mean you have to break up with the author’s work or write a rage review. This has happened to me several times, and without mentioning any titles or authors, here are a couple things a disappointed reader can do (without being angry or hurtful).
Pretend it didn’t happen. Quietly remove the book from your to-read or read shelf and don’t post a review.
Write an honest review. Without attacking the author, list reasons why the book didn’t work for you, and just state that although you enjoy this author’s other books, this one just wasn’t for you. Maybe you leave a rating, maybe not. There is nothing wrong with criticizing a book as long as you aren’t hateful about it.
What I don’t recommend is leaving an automatic gushing five star review just because you feel obligated or are worried about saying something contrary to the majority of an author’s fanbase.
Occasionally, an author makes decisions with characters that you simply can’t accept, like killing off the hero/heroine or pulling a romantic bait and switch. It’s an author’s prerogative to do whatever they wish with their characters, their world, and their story. But it’s also a reader’s prerogative whether to continue reading or not. Sometimes, you just have to say goodbye.
But, I think in most cases, a reader can continue to enjoy an author’s work, even if they don’t fangirl/boy over every single thing they write. Don’t feel guilty. We all have different reactions while experiencing a book.
