Tsithma Lockheart- A Dark Ending {One death... one book... to end it all...}

What's the opposite of Amethist? The one and only fink... Tsithema. Tsithema is a 23 year old girl with the need to destroy and cause mayhem. She wasn't born.. she was created. She came from Amethist's darkest side. The darkest part of her mind. This is basically after Book 2 of "Mr. Baldi's School House"- after Amethist developes her dark side.. I don't actually know... what this is about.. I'm just winging it... so yeah! Enjoy!!!
