From Booklist
This concluding volume of the Navigator series begins 10 months after Owen killed the Harsh king, and the villainous Harsh are preparing their revenge. Mounting a mighty invasion, they plan to turn Earth into an icy wasteland, and once more, the Resistors must be awakened to defend the world. The action is intense and mysteries are cleverly solved as McNamee skillfully weaves multiple plot strands together. The large cast of characters and ingenious contraptions are as intriguing as ever. The conclusion is wholly satisfying, yet McNamee leaves the door slightly ajar for future adventures. Grades 5-8. --Lynn Rutan
