From the publisher:

Askold, with old and new friends, once again has to defend the Earth from the Navi, who have already begun to implement a plan to enslave it. The Feds do not give up their villainy in the ancient Ukrainian history, and kidnap a prince. The most popular of the archangels is travelling along the Milky Way, and that path leads him to Kyiv. A hacker has to figure out how to put four and a half billion years into a flash drive. As usual, the house and the demon come in handy for the creative community of people and entities, and at the same time for our world. Speaking of adventures, there are plenty of them in this book.
