Petra was in the school library, and she was looking for a book for study. As she got deeper and deeper between the old bookshelfs, she found a very very old book. It was opened a lot time ago, she could see it from the dust covering it. Well, this was partly because nowadays rare amount of people use libraries, and partly because the book was written in hungarian. Petra did not know how had this book got here, but as her mother was hungarian, she could read most of the book. She realized fast, that it was a spellbook. On each page there was a magic spell, with a drawing and an explanation about the effect. Guys growing extra arms or legs, turning into animals, turning into girls, growing or loosing muscles, getting younger or older. The drawings were really realistic, even you could see the pain on their faces. Petra knew, that this is going to be a fun day. But on who shall she try it first?
