With attention to detail and scientific fact, Lung creates a credible and fantastical vision of the universe. A heightened state of suspense is maintained as Buck, with the help of his DNA replicated, extremely intelligent children, and Captain Kay, must outsmart the more powerful Craylons in order to save their race and perpetuate peace. The Echoes embody the virtues of humanity through their deep-seated love and vision for world peace, while the Watcher's detached indifference adds subtle humor to the scientific work. Readers will be kept on the edge of their seats until the conclusion.
