The ambitious, long-planned raid on the Grik Empire has grown dangerously ill defined. Only Matthew Reddy, commander of the old destroyer USS Walker, seems focused on the original intent.

While many Lemurians see an opportunity to reconquer their stolen homeland, others--Lemurian and human--have their own agendas, which could compromise the Alliance. Complicating matters further is Reddy's suspicion that his task force is being stalked by some unknown power bent on aiding the Grik for reasons of its own.

As the raid begins and chaos reigns, Reddy has no choice but to risk everything in a desperate act that results in a sprawling, nightmare battle on the beaches of "Grik City," on the very decks of Walker, and in the labyrinthine passageways of the Celestial Palace itself. The final cost could be more than Matt Reddy--or the Alliance--can bear.
