This is the first book in a trilogy set in the same world as the Black Magician series, centers on Lorkin, the son of Sonea and Akkarin. Sonea is much in the background, although Dannyl plays a prominent part, at least in this first book. I thought the story was good, although not as compelling as the Black Magician's, but Trudi is a good writer and keeps you turning the pages. You will get far more out of this trilogy if you have read the Black Magician series first, because much of the background is left unexplained. All in all, the Traitor Spy trilogy is a good read.
