Have been trying a new tack with the "Sky full of stars" Sci-Fi MSS. In order for the backstory to work more smoothly with the rest of the narrative I've changed the beginning, adding a four thousand word section that makes for a more dramatic opening. At the other end, I've found myself writing another section to wrap up all the loose story threads yet leave scope for a follow up.
Haven't decided whether to kill the hero off or not. Rather like one of those eighties soap operas where characters come back from the dead to satisfy audience demand. Well I haven't really got an audience yet, but I live in hope. Upbeat or downbeat ending? Decisions, decisions, decisions.
