From the world of Dreaming Death, we follow Amal, Lady Horn as she and her guards try to preserve one of the great secrets of Larossa: an abandoned Fortress. Amal, the chief of the Oathbreakers, is one of only a handful of people aware of the true dangers the abandoned Fortress of Salonen presents. The Cince Empire wants its secrets, and will do anything to get someone inside. Now the Horn Family must decide whether to wake the sleeping Fortress so it can defend itself against the Cince...or kill it forever. Dalyan doesn't know why he was sent to find the abandoned Fortress, what makes it worth the time his masters invested in training him. When the Horn arrest him for trespassing on the glacier beneath it, he goes with them willingly enough. After all, he didn't return to his masters on schedule, and now they're trying to kill him. But more than that, he feels drawn to the abandoned Fortress, as if he belongs there...
