The Sixty-Eight Rooms is a magical tale set in Chicago in the present day. On a field trip to the Art Institute, Ruthie and Jack discover a key that allows them to shrink down and explore the Thorn Rooms. The Thorn Rooms are miniature rooms from different times and places in history. Ruthie and Jack are thrilled just to explore the rooms, but they are even more excited when they discover that the rooms are actually portals that allow them to travel to different times in history. But how does it all work? And has anybody been in them before? Ruthie and Jack put together the clues to unlock the secrets of the Thorn Rooms. A very fun read and excellent on audio. Great for fans of Indian in the Cupboard or From the Mixed Up Files of Mrs. Basil E. Frankweiler.
