Simply put, a fantastic ghost story. Like a horror film from the 80s updated and put in novel form.
Three things I learned about writing:
- 3rd person omniscient works only if you stay out of characters' individual perspectives. Say what happens, and report what they think, but as an outsider
- Tragedy for a minor character has more impact if we spend some time with them first, however little, to see how they act normally
- Remember that characters only know what they see, and that can mislead them sometimes. That's okay. Let them be wrong when they should be wrong, so that when they're right it'll feel like triumph.
