Stiles/Hermione.
Teen Wolf/Harry Potter crossover. Obviously AU. Screwed with the timelines (brought HP forward.)
AU from 3B and Book 7. PTSD Hermione. Stiles whump.

After the death of her parents and the effects of the war, Unspeakable Hermione Granger runs to the home of her long-time friend and pen pal. What she finds, however, is not the full-of-life boy she expects.
Stiles Stilinski is lost. Drowning in nightmares, barely able to tell reality from dreams after the defeat of the Nogitsune; an event which has both mental and physical consequences from the young man. When a face he thought he'd never see bursts down his door, Stiles begins to question whether that, too is a dream. And if it is, does he really want it to end?
Mieczysław. Hermione.
Never give up, never give in.
They made a vow on parchment and paper.
To always be there; to care for each other; to love each other unconditionally.
Always and Forever.
