From the cover:
As all attempt to hide and heal, Train's conscience grows deep... Deep enough to make the decision to leave Chronos for good. Unfortunately for him, the life he has left proves unwilling to let him go. Sought by both the Chronos Numbers and the new Taoist rebels working against them, the former assassin loses faith when he loses a friend. But his newfound companions, Sven and the young bio-weapon Eve, teach the stray Black Cat a new way of life...
