In this intricate, magnificently imagined sequel to Blue Balliett’s international bestseller, Chasing Vermeer, supersleuths Petra and Calder, along with Clader’s old friend, Tommy, are cryptically drawn into another art mystery – this time involving a Frank Lloyd Wright architectural masterpiece, the Robie House.

When the kids’ sixth-grade class attempts to save the Hyde Park landmark from demolition, eerie events are reported: Voices float out from within, shadows shift behind the art-glass windows, even the roof moves! Suddenly, a well-meaning art restoration project turns into a frightening search for ghosts, hidden treasure, and a coded message left behind by Wright. In this tangled web where life and art intermingle with death and danger, can the kids pursue justice and escape with their lives?"
