Beacon Hills' community becomes laced with demons who are wanting something in particular and the only one who seems to know what they're doing is Stiles Stilinski's sister Addison. It seems the innocent little one isn't as clean as everyone though and only big, bad Derek Hale is willing to give her the time to explain. The King of Hell wants the Eclipse Child, a special person that he can weaponize to end the world. It's known to run in the blood of the Stilinski's maternal line, but the only problem is that neither side of the battle knows which twin is the right one. The King is willing to shed blood to obtain his prize, but the wolves and hunters of Beacon Hills are willing to do just the same to fight him off and take their town back.

[ BOOK ONE ] ❝ there are two things in life for which we are never truly prepared; twins. ❞ Kasey McCall is the twin sister of Scott McCall... while they look similar, they couldn't be more different... but one thing is for certain, they always have each other's back. In the aftermath of Scott getting bit by a werewolf, their relationship is put to the test as Scott attempts to navigate high school with the added perks of being a teenage werewolf. Kasey sticks by her brother, alongside his best friend Stiles... who may or may not be in love with her. There's no telling what will come of their unwanted invitation into the supernatural side of Beacon Hills. Who's afraid of the big bad wolf? Certainly not Kasey, but her brother becoming one... now that might scare her. [ s1 & s2 ]
