The Book of tentacles

In a world where magic rules and people live side by side with magical creatures, something terrible happens. Something that threatens the life of all things. And that's when you enter the world. But you don't enter it for the first time, you realize that you were already here, you just don't remember your past. And the ancient symbols shine on your hands indicate your distinction from humans. And it is up to you to find out what kind of life you lived before and, most importantly, how you are going to live it now. The only thing you know for sure is that you have the power to change the whole world. And you decide what it will become.
