I enjoyed the first book so much I couldn’t wait to read the second adventure. In this sequel the drama is that the key is stolen. There have also been a string of art thefts and it all seems to be connected. What was most interesting was the same as before-when the kids go into the little rooms and explore. This time they’ve discovered the special connection that makes some of the rooms be “alive”-that is, they can walk outside the room into the time and place where it is set. I thought this was a good follow up.
