The Pull of the Tide (слэш)

Stiles appears alone at the doors of the emergency room the morning after the full moon, covered in blood with a deep slash torn across his left side. He's suffering from hypovolemic shock and barely conscious and he won't tell anyone what happened—not his hospital appointed psychiatrist, not his father. Not even his pack.
The list of suspects is disconcertedly short. There were only seven others in the woods with Stiles that night: Derek, Scott, Boyd, Erica, Isaac, Jackson and Allison. And none of them remember the night in quite the same way.
