This book by Jerry Pournelles daughter continues the Empire of Man/Motie contact story from an unexpected angle.
None of the story takes place in the Mote system. Instead the story takes place on New Utah, a colony of the first empire about to be assessed for entry into the empire.
It is a deeply divided planet colonised by waves of religous fundamentalists at odds with each other.. It also has a secret hidden in the outback and protected by the original colonists, A motie civilisation.
The story is very very slow to develop and never reaches the pacing or tension of the original books. But it has many elements from the previous books and also does homage to other Pournelle books like King Davids Spaceship.
Its a lovely wrap up on a more positive note than the previous books, Its got a style of its own.
