Shulkana's Box

Gulshat is thirteen years old. She lives in Bashkortostan, surrounded by the love of her family. But suddenly, something incomprehensible starts to happen: she notices that all the grandfathers and grandmothers in their village have disappeared! The girl raises the alarm, but for some reason, no one believes her, and everything that is happening is not just a coincidence; someone is definitely behind it all!
Why? Simply because her grandmother left the girl clues. And indeed, it turns out that the missing are held hostage in an underground world, and to save them, they need to get there, survive, and defeat a crazy witch. However, the mission almost fails at the first stage. Fortunately, Gulshat gains a new friend, capable of walking between worlds to help. But first, they need to save themselves, as a hunt has been declared on them.
