Fate (Derek Hale X OC)

Mercedes McCall spends her summers working with her father and the FBI. When she isn't with her father she's in her hometown of Beacon Hills, attending high school, going to parties, arguing with her twin brother, and helping her mom at the hospital sometimes.
She doesn't expect her sophomore year to be surrounded by the supernatural or hanging out with her twin and his best friend more than her own friends.
How does Derek Hale factor into her new normal? Why does the Alpha seem to follow her around after she meets Derek? And why does she feel a strange pull towards the blue-eyed beta? Find out in Fate.
