Of Power & Darkness - T.B. Wiese

Thaeia now knows who she is and what it means to have her power.
That truth has broken her. 
The darkness of her magic threatens to consume her in her grief and anger. She’s like a crashing wave of violence and rage. Her friends are unwavering in their support, but Thaeia fears even they may not be able to survive what she’s unleashed inside herself ...
Because now that she knows the truth, the only thing left is ... revenge.
