In her eighth year of Hogwarts, Hermione is suffering from a secret; her inability to sleep without walking. Taking her refuge in the restricted parts of the castle, the ones still damaged from the war, she comes across an unlikely companion to share her sleepless nights with. (Dramione).

After returning for her 8th year at Hogwarts, Hermione finds that she can't get a good nights rest- no matter how hard she tries. For her, sleeping means walking, oftentimes to the restricted and still tattered parts of the castle. On top of it all an unlikely alliance with an enemy, one who suffers from the same exact affliction, might just be her only solution.
