Herald Mags, the King of Valdemar’s Herald-Spy, has been developing a clandestine network of young informants who operate not only on the streets of the capital city of Haven, but also in the Great Halls and kitchens of the wealthy and highborn. In his own established alternate personas, Mags observes the Court and the alleys alike, quietly gathering information to keep Haven and the Kingdom safe. Mags and Amily will have to track down someone who leaves few clues behind and thwart whatever plans have been set in motion, and quickly—before terror turns to murder.
