Early on in the book Emile and bram go to the opera together. But we don't see them interact at the opera like at all, and then afterwards Emile tells-not-shows how much he's starting to like bram. I was like hmmm ok that's a weird choice. And there were a few things like that that made the romance(s) not work that well for me. The while gothic horror thing did work... The empty sarcophagus, the mysterious affliction, the secret tunnels. I liked that it wasn't snarky or winking at us about the allusions to the classics, (I've never read the source material specifically but the general feel). 

Like some other reviewers, I found the pacing odd. The tension was ratcheting up but could have ratcheted up in fewer cranks. There was not even anything supernatural for the first 2/3. And the telling not showing made for some draggy bits. 

But overall-- I liked it. Not able to quantify the liking but overall positive feelings.
