Harry Potter has just witnessed Lord Voldemort's return to power. After winning the TriWizard Cup and losing a loyal Hufflepuff, Cedric Diggory, Harry knows the second wizarding war is about to begin. Although, no one will believe him, which will only drive him to make his point more known. Meanwhile, the Order of the Phoenix is, once more, up and running, and Harry is left in the dark; he starts to wonder what Professor Dumbledore has up his sleeve, and why he wasn't informed sooner of this group of wizards, most of whom he is familiar with.
At school, Harry will have to get past the outrageous Dolores Umbridge and her horrid Inquisitorial Squad by forming Dumbledore's Army, a band of his classmates, of all ages, learning magic to prepare to defeat Voldemort. He teaches them basic spells, on account of their lack of teaching from Professor Umbridge, in order to make themselves more equipped for when that dreaded day finally arrives. Will Harry be able to defeat the Dark Lord, with or without his friends help? Or will fate not be so kind?
