What name would be best for a book: -alien alert -top secret or -area 51?

Pleace tell more details about your story. It makes it easier to com up with a titel.

I think "area 51" is the best, because it sounds more open. So people want to know what the titel means and they gona read the story.

But i think there would be a book with a simular titel like that. Meby a titel like "the hidden signs" can be oke to.
