"Harry Potter and the Order of the Phoenix" by J.K. Rowling

Harry Potter is about to start his fifth year at Hogwarts School of Witchcraft and Wizardry. Unlike most schoolboys, Harry never enjoys his summer holidays, but this summer is even worse than usual. The Dursleys, of course, are making his life a misery, but even his best friends, Ron and Hermione, seem to be neglecting him.
