The Executors. Book 4. The Sword of Tamerlane

After the disappearance of Goreslava, Katya returns to Krasnoyarsk, where she lives under the supervision of Dr. Raul Moiseevich until she comes of age. The girl finishes school and enrolls in college, and all she wants is an ordinary life,... without having to engage in magic or communicate with her father.
Meanwhile, chaos descends upon the world in the form of wars, diseases, and earthquakes. Each time, a mysterious woman in black is seen at the scene, appearing from nowhere and disappearing into nowhere. Katya realizes that Goreslava might be behind this, and if she finds her sister, perhaps she can stop the disasters. Flavius and Temnovit are also searching for Goreslava; one wants to become the master of all misfortunes, while the other aims to conquer the world of humans.
Katya discovers a trace of Goreslava in the Caucasus, and together with the Guide, they secretly embark on a dangerous journey. They will visit an abandoned aul, fall captive to djinns, meet the Mother of All Sorrows — Rokhulay, and face the terrifying riders of the Apocalypse! Will the heroes be able to stop Temnovit, find Goreslava, and save the world from destruction?
