This book completes the Spirit of Empire series of five books. The war enters its final phase . . .The Queen may have defeated the rebels, but most of them do not know it yet. Waverly's Raiders are still fully engaged as they return one world after another to the fold.It's time to take the war to the Chessori, but how? Where are they? The Chessori domain is as large as the Empire, and the Empire knows almost nothing about it. Ellie's Knights will, as always, be called to give everything that they are, but this time they are called to be explorers as much as they are warriors. Again, all players will play.
