(2010)
(The fourth book in the Known Space series)
A novel by

 
 
Since fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have--just barely--survived one crisis after another. The rebellion of their human slaves. The relentless questing of the species of Known Space. The spectacular rise of the starfish-like Gw'oth. The onslaught of the genocidal Pak.

Now fresh disaster looms, as though past crises have returned and converged. Who can possibly save the Fleet this time?
