My writing group told me to cut my favorite character and they were right.
For a year I worked on a fantasy story with a talking cat named Malkin. I loved him, gave him all the best lines. My group in Seattle read the third draft and said, flat out, 'He adds nothing. The plot moves fine without him.' I was mad for a week. But I tried a version without Malkin, just to see. The story got tighter, the main character's journey became clearer. It hurt, but they were correct. It was a good lesson in killing your darlings, even the furry ones. Has a writing group ever told you to cut something you really loved, and did you listen?
