The twelfth and final book of Evgeny Gagloev's fascinating fantasy series. The action takes place in the city of St. Erinburg, where the action of "Mirrors" and "Pardus" took place. Each of the twelve books in the series is tied to a specific zodiac sign.The day that the Light Ones had been so afraid of, that the Dark Ones had been dreaming about for centuries, had arrived. The Great Mother of Snakes performed a ritual, the Fiery Dragon was freed from the ancient shackles and began its incarnation in our world. A terrible battle is coming between good and evil. Evil spirits, mavks, bats, and Fire Wolves have invaded Klykovo, besieging the clock tower, where three Pandemonium students maintain a protective dome over the city and surrounding area. As long as the dome is intact, as long as the Light Ones are on the defensive, the evil spirits will not leave the city, but help from St. Erinburg will not come either. Old friends and enemies reveal their cards, immortals die, the dead come to life, Ophiuchus is exposed. But most importantly, Timofey seems to know how to destroy the Fire Dragon.
