"Grandma Witch: Adventure Four" is the fourth book in the Adventures of Alex and Katie series. In each of the books, Alex and Katie enter a different Russian fairy-tale and change the ending by their actions. In "Grandma Witch: Adventure Four," they embark on the journey to rescue a little girl from the three-headed dragon. But they soon find out that the problems they are about to face are much more serious than they could have anticipated. Baba Yaga, the Russian witch, immersed the whole forest into total darkness by capturing the Guardian of Light and his horse. It is up to Alex and Katie to find the Guardian of Light and bring sunlight back into the forest. They have to be brave and clever as they cross dangerous rivers, find the hut on chicken legs, make potions, and learn what it means to be smart and kind. An exciting new book in the series!
