From Publishers Weekly

Starred Review. Weber (At All Costs) launches an epic series with this gripping far-future saga, which springboards off the near-destruction of humanity in a massive war with the alien Gbaba. The survivors of the human race retreat to the planet Safehold, where they sacrifice basic human rights—and an accurate memory of the Gbaba—for the preservation of the species. The colony's founders psychologically program the colonists to prevent the re-emergence of scientific inquiry, higher mathematics or advanced technology, which the Gbaba would detect and destroy. Centuries later, cultural stagnation on this feudal but thriving planet is enforced by the all-powerful Church of God Awaiting. But one kingdom—with the aid of the war's last survivor, a cybernetic avatar that awakens to reinvent itself as a man named Merlin Athrawes—risks committing the ultimate heresy. Shifting effortlessly between battles among warp-speed starships and among oar-powered galleys, Weber brings the political maneuvering, past and future technologies, and vigorous protagonists together for a cohesive, engrossing whole. 15-city author tour.(Jan.)

From Booklist

Starred Review Earth has been destroyed by an alien invasion, and survivors are clinging to a precarious and primitive existence on a planet they have named Safehold. But they are divided into two major factions: a theocratic church opposed to all technological progress, and a secular class of aristocrats and merchants who support not only technology but expanding the habitable area of Safehold. There are factions and internal conflicts on both sides, and each has infiltrated the other. A good many of the book's main players are seafarers and naval officers, and they sail Safehold's seas in ships that Horatio Hornblower might find familiar. They are drawn as well as one expects of Weber, although they are so numerous that, despite the appended cast list, readers may feel mnemonically challenged. Staunch Weber fans may be disappointed by the lack of any Safehold life-form as irresistibly charming as the treecats of the Honorverse (the world of his space-faring heroine Honor Harrington). Safehold's abundant pelagic life is mostly predatory and sometimes outright deadly, and its land dwellers are only slightly cuddlier. Altogether, there is enough conflict to allow a natural storyteller like Weber to make a large, splendid novel that opens another saga. The saga being Weber's form of choice and high achievement, hopes for the rest of it are definitely elevated. Roland Green
