I’ve been working on a horror short story, and I think it’s got potential. The buildup is there, the suspense works, but the ending? Total flop. I just can’t stick the landing! I want that jaw-dropping twist or chilling final line that leaves readers haunted, but every attempt feels forced. I’m wondering if book ghostwriting services could help craft a killer ending (equivoque yet interesting). Has anyone here used a ghostwriter for just the conclusion of a story? Do they collaborate with you or come up with ideas independently? I’m torn between sticking it out on my own or trusting a pro to give my story the ending it deserves. Would anyone like to share an advice?
