The Orb of Odenis

Hermione Granger is the most brilliant witch of her time, winning a special award for getting the highest marks and for doing the most subjects at the Hogwarts School for Witchcraft and Wizardry. However, she is on the brink of disaster as her grief over the death of Harry Potter during the final battle of the war begins to take her life. Meanwhile, the magical world is somehow losing its power, with wizards and witches unable to perform magic.

Ron and Hermione get a strange letter from the Ministry of Magic summoning them to a special meeting. But they have a problem: how do they get there? Time is running out and their options appear to be limited.
