Dear reader! Imagine that you have somehow miraculously been transported to a parallel world, in some ways very similar to ours, but in many ways completely different. Now imagine that you are a private detective or a journalist. And that you don’t have to look for adventures - they find you themselves. However, if you have read the book “Hill of Demons”, published in our library, then you can already guess what will be discussed. Believe me, “The Door to the Underworld” will give you no less joyful experiences - together with its heroes you will fight ghouls, make your way through the dark labyrinths of underground passages, expose cannibals, fly on a magic carpet and experience the witchcraft powers hidden in the magical crystal. And you won’t even notice how you get to the happy ending, because such books only have happy endings.
