Agents of the Imperial Special Investigation Service 

The first great space opera decalogy of the 21st century, this boxed set represents the first time all 10 books have been gathered together in a single volume. It follows the exciting adventures of undercover agents working to preserve the peace and unity of a galaxy-spanning empire, despite treachery that turns up around every corner. The books include:

Tsar Wars
Treacherous Moon
Robot Mountain
Sanctuary Planet
Stellar Revolution
Purgatory Plot
Traitors‘ World
Counterfeit Stars
Outworld Invaders
Galactic Collapse

Buying the books in this boxed set represents a saving over buying each volume separately.
