Summary: In an alternate New York City, three seventh graders rush to solve a century-old puzzle that they hope will save their home. When the unique building they live in is bought by an uncaring billionaire, twins Theo and Tess and their friend Jaime decide to try to solve the Cipher. Created by the Morningstarr twins in the nineteenth century, the Cipher has baffled people for years, including the twins’ grandfather, now suffering from dementia. When the kids discover a letter sent to their grandfather that appears to be from one of the Morningstarrs, they think they have stumbled upon a new version of the Cipher that may lead to its solution and the treasure that awaits the solver. Rushing from one adventure to the next, the reader learns about some of the steampunk-inspired inventions of the Morningstarrs that are part of daily life in this version of NYC. Although the kids discover important clues, the case of the Cipher is still not cracked by the end, and a cliffhanger will leave readers anxiously awaiting book 2. 496 pages; grades 4-8.
Pros: Fans of Rick Riordan will eagerly consume this tale featuring three gifted, quirky protagonists, an intriguing mystery, and plenty of adventure.
Cons: The kids seemed to solve the extremely difficult puzzles with remarkable ease…although at least some of that may be part of the mystery.
