Komarr

Description for KOMARR by Lois McMaster Bujold:

Komarr could be a garden--with a thousand more years work. Or an uninhabitable wasteland, if the terraforming fails. Now the solar mirror vital to the terraforming of the conquered planet has been shattered by a ship hurtling off course. The Emperor of Barrayar sends his newest Imperial Auditor, Lord Miles Vorkosigan, to find out why.

The choice is not a popular one on Komarr, where a betrayal a generation before drenched the name of Vorkosigan in blood. In the political and physical claustrophobia of the domed cities, are the Komarrans surrounding Miles loyal subjects, potential hostages, innocent victims, or rebels bidding for revenge?

Lies within lies, treachery within treachery --Miles is caught in a race against time to stop a plot that could exile him from Barrayar forever. His burning hope lies in an unexpected ally, one with wounds as deep and honor as beleaguered as his own.

This is #14 in A Miles Vorkosigan Adventure.
