The Clockwork Ghost: York

In 'The Clockwork Ghost: York,' the second book in Laura Ruby's series, Tess, Theo, and Jaime continue their quest to solve the Old York Cipher, a puzzle laid out by the Morningstarr twins, the architects who built an alternate New York City filled with marvels. As the trio delves deeper into the mystery, they encounter a mechanical bird that carries a cryptic message and hints at a hidden history of the city. The stakes rise when they realize they're not the only ones after the treasure; a sinister figure named Leo Biederman is on their trail. The children must navigate through secret tunnels, decode more complex clues, and confront the city's dark past, all while their home in the Morningstarr apartment building is threatened by real estate developers. 'The Clockwork Ghost' weaves a tale of friendship, perseverance, and the power of ingenuity against a backdrop of steampunk technology and urban intrigue.
