Luck in the Shadows, Stalking Darkness and Traitors Moon are the first three. Then Shadows Return, The White Road, Glimpses (a collection of Flewelling's Nightrunner short stories, illustrated with submitted fanart by readers), Casket of Souls, and the final book (for now, at least) Shards of Time, is due for release in April.
