This is the last in a trilogy set in a generation starship, called Jacob's Ladder. 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.
The end of the journey is in sight, a star system, which has two planets, one habitable, the other with a toxic ecosystem. The Captain, Perceval, is a Conn, a member of the fratricidal family that run things. All seems under control until mystery raiders kill her mother, stealing her 'null blade', a special sword and an old book from the Lbrary. While it looks as though old wounds will be re-opened, a new type of problem presents itself. One of the planets found to be inhabited. While Jacob's Ladder has been on its journey, humanity has leap-frogged its technologies and reached the stars first.
The narrative in this book is unlike the preceding two as it flips from the feuding Conns to the citizens of 'Fortune' who are 'right-minded' humans, eschewing the violent emotions the Conns treasure. A conflict in ideologies thus looms as large in this volume as the feuding between the Conns was in the preceding volumes. Premier Danilaw on Fortune and his security Chief, after debating the issues, decide to rendezvous with the incoming ship and discuss the options. But things do not go to plan...
On the face of it, this novel sets up a unique scenario with plenty of internal and external conflicts which should result in an explosive finale...but things fail to boil over at any point. It just seems to stop, which is a shame considering the pedigree and plotting of the previous two novels.
