Nerd - Stiles Stilinski

This story is inspired by the TV show "Teen Wolf" from director Jeff Davis.
It is an OC x Stiles slow-burn/"enemies to lovers" love story.
This story does NOT INITIALLY follow the event timeline of the show. (I may add some parts)
shorter chapters.

Cassandra Hale, Derek Hale's younger sister.
When she was 10 and Derek was 16, a fire was started at their house by Kate Argent (a hunter) and killed their whole family. Derek was burdened with the responsibility to keep his little sister safe and out of foster care.
Now, the two siblings are currently living a quite normal life for two werewolf siblings. Cassandra (Cass - Cassy to Derek) goes to Beacon Hills High School (she is now 16, a Junior) and Derek stays in the loft usually. Both living off all the deceased Hale's money for car and phone bills. Until one night changes everything. There's an Alpha running the streets of Beacon Hills and he's creating a pack. Starting with a scrawny teenage boy who goes to Cass' school...Scott McCall.
How will Derek and Cassandra help him learn the way of the wolf and stop the crazed Alpha at the same time? Building relationships on the way has it's consequences.

For more mature audiences!
