I am very heavily leaning towards killing my main character at the end of my book/series. He would die just after the resolution of the main plot. The resolution/epilogue of side plot arcs would be taken over by the protagonist's best friend and love interest. My question: Does the death of the protagonist kill the ending of the book for you? I wouldn't want to write in the tragic ending if it would be too depressing. It's supposed to be bittersweet, not miserable.
