A twig snaps, and then Stiles hears breathing and the rustle of leaves. He strains to get a better glimpse into the darkness, but it’s pointless. There’s nothing but a black void.
It's Stiles' senior year, and he's trying to concentrate on normal things - like the lacrosse championship, spring break, prom, graduation (and definitely not Derek) - when he starts having nightmares and waking up in the middle of nowhere. Oh yeah, and he's being haunted by a hag. Great.
There's a relentless dark shape tearing through the pack and that's only the half of it. Stiles just wants to sleep and stop being haunted by the faces of his night-time tormentors. His dad thinks he's suffering from post-traumatic stress, Scott thinks he's suffering the after-effects of the ritual; Stiles thinks they're both reasonable theories, except for the part where Derek Hale is the only thing that can take his nightmares away and it seems that fact is no coincidence.
