When his wife and unborn child are abducted, Grant Wilson races against the clock in this pulse-pounding thriller packed with riddles, danger, and the desperate fight to save his family, perfect for fans of Adrian McKinty's The Chain. They took his wife. They took his unborn child. He only has hours to find them ... or they're dead. Grant Wilson has never been happier. He has a wife he loves, a home in the country, and a brand-new baby on the way. But all of that shatters when two masked men abduct his wife, Avery, in broad daylight. The instructions Grant receives are bizarre: If he wants Avery back, he must solve a series of riddles that arrive one after another-and the clock is ticking. With every piece of the puzzle more outrageous and complex than the last, Grant knows he's playing a dangerous game. But he's determined to do whatever it takes to save Avery's life ... even if it kills him.
