Traitor's Moon - Lynn Flewelling

As the war between Pleminar and Skala continues, there are growing rumors that Skala's ancient ally, Mycena, is about to join with the wealthier Pleminar, cutting Skala off from all trade routes. Now Alec and Seregil are sent on their most daring mission yet: convince the people of Aurenen to join Skala and end the war. nMaster spies Seregil and Alec are no strangers to peril. Their assignments, nightrunning for wizards and nobles, have led them into many deadly situations. But sometimes the greatest danger can lurk beneath a Traitor's Moon. . . . nWounded heroes of a cataclysmic battle, Seregil and Alec have spent the past two years in self-imposed exile, far from their adopted homeland, Skala, and the bitter memories there. But as the war rages on, their time of peace is shattered by a desperate summons from Queen Idralain, asking them to aid her daughter on a mission to Aurënen, the very land from which Seregil was exiled in his youth. Here, in this fabled realm of magic and honor, he must at last confront the demons of his dark past, even as Alec discovers an unimagined heritage. And caught between Skala's desperate need and the ancient intrigues of the Aurënfaie, they soon find themselves snared in a growing web of treachery and betrayal.n
