Clockworks being mostly about the past - the house, the caves, the strange and terrible door, and the keys and how they came to be made and why. All that goes back to the Revolutionary War, but closer in time was the father of Tyler, Kinsey and Bode, and how he and a group of friends used the keys to have the most amazing year of their lives, and how in the end it all went dreadfully wrong, leading to the current state of terror. And it turns out Lovecraft wasn't just namechecked. It all clicks together like, well, you know. At the end the plot has moved forward only in couple of small but crucial ways, but the decks are cleared and the blanks are filled in and we're ready for the big finale. Who, as they say, will survive and what will be left of them?
