The Shadow of Saganami is a science fiction novel by American writer David Weber, published in 2004.

The story focuses on the shakedown cruise of the Edward Saganami-C-class heavy cruiser HMS Hexapuma (nicknamed Nasty Kitty), commanded by Captain Aivars Terekhov, a war veteran and former prisoner of war who has only recently been cleared for return to active naval service.

One of the major systems is Montana, where Stephen Westman bombs multiple government facilities without causing a single casualty.

The remaining Mesan crew quickly surrenders and eventually provides information on an OFS task force being secretly sent to settle the unrest in the Cluster.

After threatening to destroy all of the remaining military infrastructure in Monica, Terekhov is able to hold the system long enough for reinforcements to arrive from the Talbott Cluster.

After repairing his ships enough for them to get underway, Terekhov and the Hexapuma return to Manticore where Queen Elizabeth III and the Home Fleet welcome them and applaud their service in the Cluster.
