Fergus, appointed Interrogator for the god Tezcatlipoca in England with the mandate to suppress or convert the native Christians, must find a way to work with the local priests of Tezcatlipoca and that god's rival, Quetzalcoatl. He finds himself caught in a delicate balance as a go-between for the people trapped in the fortress, and the rebel forces surrounding them. Captain Mixcoatl's loyalty is torn as his best friend throws in with the desperate governor and his scheme to turn the Toltec province into an independent kingdom. Outnumbered and beset, Mixcoatl must once again look to the sly King of Gwynedd for assistance to raise a force to save England and the life of his pregnant wife. Rowena, maid to Captain Mixcoatl's wife, finds herself on the parapet with her mistress staring down at a rebel army, facing the final assault with a group of women and children. The fate of the Island Colonies hangs in the balance, and our three protagonists are drawn ever closer, as forces clash over who will rule the overseas jewel of the Toltec Empire.
