Killing off a character.
I don't find it difficult to comprehend the change in my writing, after all, none of my ebooks have sold in the last three years, and this leads me to a situation that years ago would have upset me - killing of a beloved character in a story - but not now.
The situation first comes to show seven years ago when friends who were following the adventures of my hero (Mark Johnson) got worried that after a bad week I'd kill off their hero; in the end, I spent days trying to write a gruesome end, but I never could do it.
The next time was when I had to kill off a character who was dying slowly in my second sci-fi series (The Word); I knew his story needed a heroic death to give his life meaning, but I cried for days after writing his finale.
Now, I woke this morning with an ending for my romance that I had not foreseen, and feel no remorse if I write the death of Kim Altland from "A Homecoming," after all the book has been on sale for two years and not sold.
I haven't decided how to end "The Reunion," or even if I shall end it, nobody cared what happened in the end.
