Not only in the Hogwarts School of witchcraft and magic, mysterious and terrible events take place. And not with just Harry Potter. Percy Jackson, a twelve-year-old American schoolboy, almost falls victim to a math teacher. It is good that the pen that Mr. Branner, a Latin teacher, gave him turns into a real sword and strikes the distraught mathematician. But Percy Jackson's woes don't end there. On the coast where they leave with their mother, they are attacked by the monster Minotaur. And Percy's friend from school, Grover, who unexpectedly came to the rescue, turns out to be not a boy, but a satire. But the main adventures begin later, when he and Grover get to the Half-Blood Camp... Rick Riordan's Percy Jackson cycle has become one of the super bestsellers of recent years.
