The Children of the Sky is the long-anticipated sequel to the Vernor Vinge’s Hugo Award–winning A Fire Upon The Deep. It is set in his Zones of Thought universe, which imagines a galaxy divided into regions that support different levels of technology and intelligence, from the easy FTL travel and posthuman Powers of the Transcend to the appropriately named Unthinking Depths at the galactic core.
The first time I read this book, I didn’t like it. I, like many others, was expecting a fast-paced adventure spanning the galaxy, such as A Fire Upon The Deep. Instead, the setting is limited to Tine’s World. I was looking for a satisfying resolution to the menace of the approaching Blight fleet, but the ahuman superintelligence stays comfortably in the background. I almost didn’t give it a second chance, but I did, and I appreciated it more the second time through. Once I got past the fact that this book was not what I was expecting, I enjoyed it, although it isn’t on the same level as A Fire Upon The Deep or A Deepness In The Sky.
The story starts 10 years after the ending of the previous book. Ravna Bergsndot leads the awakened Children, refugees from the Blight’s destruction of their home and stranded on Tine’s World. They are attempting to build a technological civilization capable of repelling the Blight with the help of the Out of Band II, the partially-functional starship that originally carried Ravna and the frozen Children to Tine’s World, and the Tines, a fascinating alien species made up of packs of 4 to 8 wolf-like creatures that act as a single individual.
Ravna and the Children have the support of Woodcarver, the ruler of an emerging empire. However, many of the Children are suspicious of Ravna’s interpretation of the Blight and the destruction of their home world, and in the far-off Tropics, a pack named Tycoon is starting an industrial revolution, assisted by Vendacious, Woodcarver’s traitorous spymaster.
