Let's run away from here!

Fourth graders of an ordinary middle school are incredibly lucky. Or maybe not so lucky - it depends on how you look at it. Their teacher (and also the principal of the school) is a witch. No, she doesn't fly on a broomstick or brew potions from bats, but she can send them to visit saber-toothed tigers or trolls, enchant a door, and show what happens inside a mobile phone. At first, the fourth graders are scared, but then it becomes frighteningly interesting. Especially for those among them who have learned to conjure themselves.
