YORKThe Clockwork Ghost (Book Two)
It was only a few weeks ago when the Biedermann twins, Tess and Theo, along with their friend Jaime Cruz, followed the secrets of the Morningstarrs' Cipher further anyone had in its century-and-a-half history—and destroyed their beloved home in the process. But the Cipher still isn't solved. The demolition of 354 West 73rd Street only revealed the next clue in the greatest mystery of the modern world, and if Tess, Theo, and Jaime want to discover what lies at the end of the puzzle laid into the buildings of New York by its brilliant, enigmatic architects, they will need to press on.
