I started a randomly-checked out library book yesterday and the first few pages are so exciting! I suspect that it is a book about time travel or set in an alternate universe, although I don't think its author believes either of those things.
It's set sometime in the twenty-first century (someone says so). An American comes to visit an Englishman who is Lord of the Manor.
And guess how she lets him know what time her plane will be arriving? She sends a telegram!
