So I finished a book a while ago that sort of us left me feeling nothing. I was very disappointed because the book was about musicians, which I am, and obviously about music, which I love. All my MSs have music themes and my next book is going to be straight up about musicians, so I was reading this for research.
But despite all these things that I thought I would love, it left me feeling stale. There was no emotion in the writing. I felt little for the protagonist and I wanted to like the love interest but I just didn't. To me, they felt like paper characters. And all the musical allusions seemed cheesy and not heartfelt. Then at the end the love interest died! I should have felt heartbroken but I didn't really feel anything. Well except anger because I didn't really understand the point of why he died.
I think one of the reasons we read is to relate to characters, especially when it comes to emotions and what they are feeling. Are they love-sick? Teenagers and adults can relate to that. But if they go through the whole book being a shell of a character, I'm not going to feel anything for them and I won't care about them. That's why I think emotions and characters are the most important aspect of a book and something that I'm working on in my MS to make sure it rings trues.
