Book Description
It was 1798 when the Morningstarr twins arrived in New York with a vision for a magnificent city: towering skyscrapers, dazzling machines, and winding train lines, all running on technology no one had ever seen before. Fifty-seven years later, the enigmatic architects disappeared, leaving behind for the people of New York the Old York Cipher--a puzzle laid into the shining city they constructed, at the end of which was promised a treasure beyond all imagining. By the present day, however, the puzzle has never been solved, and the greatest mystery of the modern world is little more than a tourist attraction. Tess and Theo Biedermann and their friend Jaime Cruz live in a Morningstarr apartment--until a real estate developer announces that the city has agreed to sell him the five remaining Morningstarr buildings. Their likely destruction means the end of a dream long held by the people of New York. And if Tess, Theo, and Jaime want to save their home, they have to prove that the Old York Cipher is real. Which means they have to solve it.

Book Description
National Book Award finalist Laura Ruby returns with the middle chapter in her epic alternate-history adventure—a journey that will test Tess, Theo, and Jaime and change their lives forever. It was only a few weeks ago that the Biedermann twins, Tess and Theo, along with their friend Jaime Cruz, followed the secrets of the Morningstarrs’ cipher further than anyone had in its century-and a-half history—and destroyed their beloved home in the process. But the Old York Cipher still isn’t solved. The demolition of 354 W. 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. But doing so could prove even more dangerous than they know. It is clear that the Morningstarr twins marshaled all the strange technology they had spent their lives creating in the construction of the Cipher, and that technology has its own plans for those who pursue it. It's also clear that Tess, Theo, and Jaime are not the only ones on the trail of the treasure. As enemies both known and unknown close in on them from all sides and the very foundations of the city seem to crumble around them, they will have to ask themselves how far they will go to change the unchangeable—and whether the price of knowing the secrets of the Morningstarrs is one they are willing to pay.

Book Description
The thrilling conclusion to two-time National Book Award finalist Laura Ruby’s epic adventure through the streets of an alternate New York City. It was only a few days ago that Tess Biedermann, Theo Biedermann, and Jaime Cruz, along with a mysterious figure from the past, managed to survive an assault on the location of the latest clue in the Morningstarr cipher—and, in the process, made a shocking discovery about their own connection to this one-hundred-sixty-year-old enigma. Now the friends are divided. Tess and Theo have no idea what the photo they found in Greenwood Cemetery means, but Jaime is convinced that they do, and that they’ve been keeping their own secrets from him. As the city continues to break around them, suddenly solving the greatest mystery of the modern world seems less important than saving their own friendship. The stakes of completing the cipher, however, have never been higher. Darnell Slant, real estate developer and owner of all the Morningstarr buildings, knows that they hold one last secret: a power that even the Morningstarrs themselves never revealed. The world has rested on a precarious balance of power for generations; now Slant and his shadowy business partners aim to unbalance it. It’s up to Tess, Theo, and Jaime to uncover the Morningstarrs’ final mystery in a desperate attempt to set things right. The world—theirs, and possibly others—depends on it.
