Наследница мага смерти/Антимаг/Колодец мрака

An unusual find falls into the hands of Inga, an archaeologist-laboratory assistant: an old ring, which is not listed in any museum reference book. That's just a unique historical artifact also turns out to be a magical artifact. And the joy of its activation instantly melts away when Inga is literally thrown out of the familiar world into another - full of evil spirits, dangerous creatures and dark magicians. Magicians who declare a hunt for a girl.

How to survive? Is there a chance to return home and what needs to be done for this? Make a deal with the white-haired demon? Seize the inheritance of an ancient sorcerer? Or… sell your soul to one very sly goddess?
