In this second book of a planned trilogy that began with The Navigator: Chosen to Save the World (2007), it has been a peaceful year since the crisis that drew Owen into the battle between the Resistors and the evil Harsh. Owen's friend Cati serves in the lonely role of invisible Watcher. Cati realizes that something is wrong, but she fails to wake the Resistors and calls once more on Owen. Together, they find themselves in a new battle against the Harsh, this time journeying to Hadima, the City of Time. Aided again by Dr. Diamond and his intriguing gadgets, they encounter unusual allies, including a one-handed Yeati. The story alternates between Hadima and Owen and Cati's home world, which is about to collide with the moon. As in the previous book, the swift action sweeps the reader along without any niggling questions about world structure. The first chapter nicely catches readers up with the back-story, and by the satisfying conclusion, many secrets are revealed along with enticing hints of more adventures to come.--Rutan, Lynn Copyright 2008 Booklist

Gr 7 Up-In this sequel to The Navigator (Random, 2007), earthquakes, tidal waves, and general environmental turmoil are on the rise, and Owen is called into action again. The moon's orbit has altered, and the very fabric of time is running out. Owen teams up with his friends from the first book and embarks on a quest to Hadima, the City of Time, to seek out a tempod and try to reestablish stability of time. Faced with deceptions, double-crossings, and the icy power of the Harsh, Owen and his friends are challenged physically and mentally at every step of their adventure. Pacing and story details are excellent with just the right amount of suspense and withheld information to keep readers wanting more. Characters are unique and suitably delineated with an appropriate balance of protagonist and antagonist attention. City of Time reads like a stand-alone novel; all pertinent details are explained. However, it would help more astute readers to be familiar with the first book. Naturally, situations are set up for the final book in the trilogy. City of Time will certainly enjoy as much reader attention as the first book.-Dylan Thomarie, Johnstown High School, NY (c) Copyright 2010.

Strange occurrences alert the two main characters from The Navigator (2007) that their enemies, the Harsh, are active and messing with time. Together with the inventive Dr. Diamond, they travel to the City of Time to find a fix for the problem and restore Earth to the proper passage of time. Favorite characters resurface while an appealing street tough named Rosie and a wise, oracular Yeati join the good guys. Surprises abound, characters aren't always what they seem and McNamee has added a truck run by magnetic power and a sailing ship that negotiates the roads of time to his sort-of slipstream collection of conveyances. But although the characters are engaging, it is the quick-paced, riveting plot that drives this vehicle. Wonders never do cease: Here's a second novel in a trilogy that doesn't suffer from middle-book syndrome. Au contraire, this thrilling adventure featuring Cati and Owen leaves the reader satisfied with the resolution, which is not at all pat, and hungering for more. Another walloping good read from a master of the trade. (Fantasy. 10-13) Copyright ©Kirkus Reviews, used with permission.
