The summer holidays are dragging on and Harry Potter can't wait for the start of the school year. It is his fourth year at Hogwarts School of Witchcraft and Wizardry and there are spells to be learnt and (unluckily) Potions and Divination lessons to be attended. But Harry needs to be on his guard at all times - his worst enemy is preparing a terrible fate for him. With characteristic wit, fast-paced humour and marvellous emotional depth, J.K. Rowling has proved herself yet again to be a master storyteller. ukryj opis
