But to do so, she must sacrifice her freedom and come to terms with her newfound powers.
Mörderin: Thána and her mother Alaina embark on a mission to reunite their family, traveling to a war-torn world where Daria is a prisoner of the invading army. With limited magical abilities, Thána joins forces with Daria's husband and friends to plan a daring rescue mission, breaking into a prison camp and relying on newfound allies.

Struggling with withdrawal from a magical substance, Thána's powers are depleted and she's hunted by the killer. To make matters worse, Katyk is missing and Thána's every move is dangerous. With time running out, Thána must find a way back to the portal before she becomes the killer's next victim.
