This novel takes no prisoners. Like the characters, the reader is continually searching for explanations and meaning. Something bad has happened to the generation starship the story takes place in. It was launched from Earth ages ago and was designed to spur the evolution and adaptation of its crew and ecosystems during its journey out. It uses an eclectic mix of technologies, both digital and biological. But where is the starship going and why?
The original ship crew were frozen after the cataclysmic events in its precursor Dust and in this book are restored in new bodies. The ship restoration is not complete as there are blind areas, that the new captain, Perceval, and her Angel Nova (an artificial intelligence) cannot penetrate. Even more worrying, the dark areas start to spread.
Perceval is a Conn, a member of the family that run things. The ex-head of the family, Alasdair Conn, instilled into his family a brutal disregard for anything except remaining in power. The fratricidal strife that drove the plot in Dust resurfaces in this novel. Tristen Conn is awakened to become the new First Mate. Along with Mallory the mage and his faithful, sentient power tool, Gavin, he is sent into the dark areas, where is it feared a secretly awakened Arianrhod Conn and her Angel Asrafil are en route to find a secret weapon hidden by the dead sorceress Cynric Conn. Benedick Conn, the father of Perceval and Tristen's brother, along with Chelsea Conn, are also awakened, as a second team questing after Arianrhod, as backup in case the first fails.
The Conns are not the only people on the ship: there are Means who acts as servants for the Conns, and small colonies of Go Backs, people who want off of the starship. But the fueding Conns are the focus and the main source of emotional trauma, plot twists and exotic locations visited in their two quests. My favourite location was an abandoned departure lounge used by a race of mobile carnivorous plants to learn about humanity by watching ancient television programmes that recycle every few years.
All in all, this novel is a really individual take on space opera, laced with the sort of characters and plots that are normally rooted in fantasy quests. It is a demanding read but worth it.
