The crazy princess and the barbarian of the North... Some would call it a perfect match, but neither is truly what they seem: Chloe was only branded as insane by her stepmother as part of a plan to assassinate her, and Callios is a fallen prince who cares deeply for his people. Chloe may have succumbed to her stepmother's schemes in her first life, but this time, she's determined to take revenge with the perfect ally at her side! Can these two make the empire pay for destroying their families?
