The Shiva option

"The Grand Alliance of Humans, Orions, Ophiuchi, and Gorm, united in desperate self-defense, have been driven to the wall. Billions of their civilians have been slaughtered. Their most powerful offensive operation has ended in shattering defeat and the deaths of their most experienced and revered military commanders. The edge in technology with which they began the war is eroding out from under them and whatever they do, the Bugs just keep coming." "But the warriors of the Grand Alliance know what stands behind them and they will surrender no more civilians to the oncoming juggernaut. They will die first...and they will also reactivate General Directive 18, however horrible it may be. Because when the only possible outcomes are victory or racial extermination, only one option is acceptable." "The Shiva Option."--BOOK JACKET.
