“Betrayal” is a science-fantasy novel by Sergey Kim, the third book of the “Order of Genocide” cycle, in the genres of battle fantasy and heroic fantasy. At the Moscow Academy of Magic, they teach you first of all not just magic—but how to rule. Plans for peaceful study and social events collapse into dust. Heirs of Polish principalities and Novgorod try to shake the power of the Rurikids. And in Moscow itself things are unsettled too—anarchists, terrorists, and criminals of every kind roam the streets. And, as usual, the Winter family steps in. Book 1. Order of Genocide. Book 2. Purgatory. Book 3. Betrayal.
