Harry Potter & the Cursed Panties of the Muggle-Born

After years of fighting the Dark Lord Voldemort, the young wizards and witches of Hogwarts are about to be put to a final test. Harry Potter, the Boy Who Lived, and his best friends Ron and Hermione, have organized a resistance named for their beloved former Headmaster; Dumbledore's Army must train in secret, because the horrible Dolores Umbridge has taken control of their school, punishing students severely for breaking her arbitrary rules.

But Harry has other problems to deal with - problems only a magical teenager might understand. When Hermione develops an odd new study habit, Harry suspects the Slytherin House may be somehow involved. This new adventure will stretch them to their limits... and if they aren't careful, it may tear them apart.
