A Ghost In The Hallway, Grinning (фемслэш)

After the war and a recovery period at the Burrow that left Hermione with crushing cabin fever, she resolves to return to Hogwarts to complete her N.E.W.T.s. Regardless of whether others think it’s unnecessary and a “bad idea.” Thank you very little.
Hermione quickly finds herself with her hands full. She juggles an accelerated workload, the lingering damage, curses, and scars from the war, and the quiet, growing pull between herself and Fleur Delacour. To make matters more distracting, Bellatrix’s hallucination appears more and more, and Headmistress McGonagall gifts her a Celtic spellbook thick with spells both temptingly powerful and dangerous. Then there’s the mysterious new Potions professor at Hogwarts, Ilsa Frost.
Beyond the castle walls, more trouble brews. Olivia Linwood targets Hermione, and her relentless drive for story and drama paints a target on Fleur. Whispers of murders and disappearances ripple through Wizarding London... especially among those with creature blood.
