Another child is dead. The fourth in five weeks. Edwina k’Abiru, who experienced a personal loss two years ago, has been recruited by the Cooperative Authority to contribute her insights as a puzzle champion to this case. With the ongoing killings, Edwina finds parallels between the murders her grandfather solved in his youth, leading her to believe the Griph Code is more than a mere cipher left as her last inheritance. These clues point her to a secluded group, which in turn lead Edwina to discoveries about herself and the perceptions of the world around her.
