Faunoe o fatuoe (Sterek slash)

Stiles has always been the vulnerable one, the weak one, the human one of the pack. That is until a chance encounter with a terrifying supernatural beast brings out something dark and powerful inside him. Its only then that he discovers his mother wasn't exactly human and she had passed both her powers and her place in the supernatural world to Stiles upon his seventeenth birthday.

In which Stiles is magical werewolf catnip, Beacon Hills is invaded by werewolves desperate to take him as their mate and immortal companion, and Derek has to chase the interlopers out of his yard.
