A young emperor’s life hangs in the balance and only the Brotherhood can save him …

Constantinople, 867—A murderous plot is afoot. Assisted by the Order of the Ancients, the emperor schemes to assassinate his son and throw the city into chaos. In response, the Hidden Ones have dispatched Assassin acolyte Hytham to join his mentor, Basim Ibn Ishaq, to infiltrate the palace and foil the emperor’s plan.

But that is not his only mission … Hytham’s brotherhood have entrusted him with uncovering where Basim’s true loyalties lie and whether the master Assassin’s personal obsessions outweigh his sense of duty. For Hytham to succeed, he must tread carefully, for Constantinople is a city of shadows, and danger hides in them all.
