I think this verb tense is future progressive. But it's been 15 years since I taught grammar, so hopefully someone smarter than me will come along to identify it.

I particularly liked a first line of a chapter in the middle of a book: "There was a demon in the room's corner, and only she could see it." Immediately i wanted to know more.

David Gemmell also often started his chapters with a cold open. It's fun to read.
