Nyx is a girl who can heal any wounds except her own.
When a king captures and murders her mother, she is imprisoned; forced to heal men of war who deem her lower than dirt and forced to marry the king she loathes the most.
Saval is a servant boy who just wants to mend his scars from the past, and to have money and food for tomorrow day.
They meet.
It goes downhill from there.
Nyx - known only by her codename in the shadows - is ranked the number one assassin in the world. No one has ever seen her or caught her. the only warning before she strikes is a crimson butterfly brooch, left behind like a promise of death. But her next target is different. Alaric D'Amato - heir to one of the richest family in Asia. Sweet. Gentle. Untouchable. A man so beautiful, he looks like he doesn't belong to this cruel world. For the first time, Nyx hesitates, for the first time she broke her own rule. She was meant to take his life, instead he might just steal her heart.
What happens when the devil falls for an angel?
And how far will she go when someone tries to take him away?
