Being Stiles’ little sister meant two things: one, you were used to chaos, and two, you knew when he was keeping secrets. Lately, he’d been acting weirder than usual—sneaking out late at night, covering up bruises, and muttering about things that didn’t make sense.

So, when he left his room unlocked one day, you did what any curious sibling would do. You snooped.

What you found changed everything. Notes about werewolves, hunters, kanimas—things that sounded straight out of a horror movie. And at the center of it all? Scott McCall.

Scott, your brother’s best friend. The same Scott who had always been sweet to you, who smiled at you in the hallways, who made your heart race in a way you tried to ignore. But now, you weren’t just looking at him as Stiles’ best friend—you were looking at him as something else. Something not human.

When Stiles found out you knew, he panicked. Scott tried to keep you out of it, to tell you it was too dangerous. But it was too late. Now that you knew the truth, Beacon Hills’ supernatural world refused to let you go.

Between hunters closing in, new threats rising, and your own growing connection to Scott, one thing was clear: you weren’t just Stiles’ little sister anymore. You were part of the pack. And there was no turning back.
