Yeah, sure, it’s good. If you like historical narratives, you’ll dig it. 

HOWEVER 

It never really fulfilled the promise of the premise, for me. What I mean is that the stories never intertwined. Neither was necessary for the other. It ended up just being two narrative threads that ran parallel to each other, each with it’s own set of characters and events- never really uniting, nothing shared save the time frame. 

And, unfortunately, one story is far more compelling than the other, but, really, how thrilling can you make architecture? Maybe if I was more into that field, I’d dig it a lot more, who knows. Actually, I would have liked to read a lot more about the exhibits and the technology on display. 

As for the Holmes stuff, so much of it is conjecture and supposition, which is necessary, because the concrete facts are so few. Maybe the book should have just been an architectural study of his hotel, I dunno. 

That’s not to say it’s a bad book, just not as good as I’d hoped it would be.
