When Winter Kim finds out that her sister is dead and that she has a brother she never knew about, only two things matter―finding what’s left of her family and killing the man who destroyed her life. Her mission leads her from St. Louis to Los Angeles back to South Korea, where she grew up.
Things get increasingly dangerous once Winter arrives in Seoul. Aided by her friends Jesse and Sebastian, Winter attempts to infiltrate an international corporation to get close to her target, a nefarious businessman named Kyung. But keeping her last remaining loved ones out of the line of fire proves difficult, and when all seems to be lost, Winter must face one last devastating decision: is revenge worth sacrificing everything for? Or can she find a spark of hope in the darkness that threatens to engulf her?
