Filled with magic, mystery, miniatures, and adventure, the Sixty-Eight Rooms is the perfect series for fans of Chasing Vermeer, The Mixed-Up Files of Mrs. Basil E. Frankweiler, and The Dollpeople! Chicago sixth graders Ruthie and Jack think they’ve learned everything about the magic of the Art Institute’s Thorne Rooms. But the magic starts to act strangely when Ruthie and Jack discover two rings that are out of place—and out of time—and a portal that shouldn’t be open but somehow is. Ruthie and Jack follow the clues to seventeenth-century England and the Brownlow house, where they meet the Brownlow’s governess, Rebecca. But Rebecca has a few secrets of her own—and she might even be in the wrong century! Can Ruthie and Jack discover the truth about Rebecca’s mysterious past, or will they end up stuck in the wrong century themselves? Their quest for answers takes them from 1930s New York City and San Francisco to turn-of-the-century China. The only one who can truly answer their questions may be the woman who started it all: the room’s creator, Narcissa Thorne. But to talk to Mrs. Thorne, they’ll have to go back in time and find her! Unlock the magic . . . in the exciting conclusion to the Sixty-Eight Rooms Adventures!

In the Art Institute of Chicago's miniature Thorne Rooms, the Thorne Rooms key and a mysterious set of rings lead Ruth and Jack to new historical eras and a woman who went missing as a young girl.

An adventure inspired by the Thorne Rooms, an exhibition of 68 exquisitely crafted miniature rooms in the Children's Galleries of the Chicago Art Institute, envisions a magical key that enables people to shrink to a small enough size to visit the rooms directly and discover hidden secrets and the mysterious activities of previous visitors.

Fans of magic, mystery, and adventure will love this rollicking sequel to The Sixty-Eight Rooms—a perfect next step for kids who love the Magic Tree House series, and just right for readers who love Chasing Vermeer, The Mixed-Up Files of Mrs. Basil E. Frankweiler, and Wonderstruck. Sixth graders Ruthie and Jack thought their adventures in the Thorne Rooms were over, until miniatures from the rooms start to disappear. Is it the work of the art thief who's on the loose in Chicago? Or has someone else discovered the secret of the Thorne Rooms' magic? Ruthie and Jack's quest to stop the thief takes them from modern day Chicago to 1937 Paris to antebellum South Carolina. But as more items disappear, including the key that allows them to shrink and access the past worlds, what was once just an adventure becomes a life and death race against the clock. Can Ruthie and Jack catch the thief and help the friends they meet on the way before the magic—and the rooms—are destroyed forever? Here's What People Are Saying about The Sixty-Eight Rooms Adventures! The New York Times: "Irresistible." Chicago Sun-Times: "Exhilarating."
