I did not discover my mistake until having thrown myself head-first into actually writing the book, and now I am faced with renaming at least one very important character. The siblings can perhaps survive with sharing initials, but the best friend has to go through a change, and after writing the entire first draft with her name very fixed in my mind, I might as well try to rename one of my own friends.
Every different name makes a slight difference in the person you imagine, and having officially made up my mind to change that girl's name, it remains now to be seen whether her personality is going to be seriously affected.
Ever stared at yourself in the mirror and wondered what other names you could have successfully pulled off? Maybe I am just weird.
