The Vanishing Stair

I thought the first book in the series was just okay, but this continuation was everything that I wanted it to be. I thoroughly enjoyed the clues and reveals and, even though I don't usually enjoy YA because of its simplicity, I couldn't put this book down once the pieces started coming together.  I also now understand that the first book couldn't be all that satisfying, because the whole trilogy should be looked at as a whole, and rating each installment individually is not quite fair.  Overall, a really fun and thrilling reading experience. I'm starting the next book right away because I just need to know more.
