The world seemed to dip and darken and I smelled wet earth and thick musk and fresh blood. The wind whipped past, like I was running. Running so fast the ground whizzed beneath me and the wind cut across my skin... Maya Delaney has always felt a close bond with nature. The woods around her home are a much-loved sanctuary - and the pawprint birthmark on her hip feels like a sign that she belongs. But then strange and terrible things begin to happen in the tiny medical-research town of Salmon Creek (population: 200). The captain of the swim team drowns mysteriously in the middle of a calm lake.

Mountain lions appear around Maya's home, and won't go away. Her best friend, Daniel, starts experiencing 'bad vibes' about certain people and things. One of those people is Rafe - the new bad boy in town.
