Genetically engineered for genius and trained for revolution, there's only one thing she can't do--forget. Gray has finally broken free of the Protectorate, but he can't escape the time bomb in his head. His body is rejecting his modifications, and his months are numbered. When Maya's team uncovers an operation trading in genetically enhanced children, she'll do anything to stop them. Even risk falling back into the hands of the TechCorps. And Gray has found a purpose for his final days: keeping Maya safe.
