Shin Sia

Aging assassin Hornclaw has seen it all, but she never expected to mentor a reckless rookie like Bullfight. As their unlikely bond deepens, cracks form in the underworld they navigate together. When Hornclaw discovers someone wants her dead, she’s thrust into a deadly game of deception. With enemies closing in and trust in short supply, survival means staying sharp—both blade and mind.

In this sequel to the famous Korean sci-fi action thriller THE WITCH: SUBVERSION, the story moves away from a confined secret lab and out into the real world. 
After a mysterious girl emerges as the sole survivor of a bloody raid on the research facility behind the top-secret Witch Program, she is rescued by a pair of civilians who soon realize the girl is both mighty and in very grave danger. However, as the assassins tasked with locating and silencing the girl move ever closer, the lives of everyone around her fall under increasingly great peril.
