Watchtower

Not sure why, but I picture a novel, with a watchtower on it. Was there a novel called that? I am not a big reader, so I doubt it's anything I ever read. But I might have seen the book cover.

Oh, wait! Isn't that a religious thing? Like one of those pamphlets they give out? I think that's what I'm seeing...

I guess that really does tell you how much I read. I equate religious spam with cheap novels.
