An isolated institute laid out in a Fibonacci sequence, hidden deep in the forest. Twenty-four labs. Twenty-four researchers. Until one of them disappears… When physicist Stéphane Douasy arrives to occupy the vacant twenty-fourth lab at the Institute for the Study of Complex and Dynamic Systems, an ominous problem rises in his wake: what has happened to his missing neighbor in Building F? When Stéphane's neighbors, a discouraged linguist and a computer scientist bent on predicting the future, discover that the missing researcher may have solved the P versus NP problem-a coup in computer science with revolutionary implications for everything from mathematics to philosophy-before vanishing, things turn stranger still, and even more menacing. Solving the mystery of the Institute and its devolution into mayhem and violence every seventh year quickly shifts from being an intellectual exercise to a matter of life and death.
