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.

Tsar Wars
Treacherous Moon
Robot Mountain

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