Finished Dark Matter quickly. It’s an Arctic ghost story. It felt slight to me: as if it’s really a short story that’s been padded out. The premise and setting are engaging, even if the characters are a little too Brideshead. The connection between the scientific concept of dark matter and the darkness of the Arctic night works well. It just didn’t need the explanation of who the ghost was. Would have been better with the ghost as a nameless, unknowable horror.
