The sad tale of women-trafficking (women! They're taken as children!) and these women being raped, beaten, and sold into a life of prostitution is told here with sympathetic characters. Why these tragedies can be tolerated in a mainstream comic book is because of the presence of Frank Castle - we know the horrors will be avenged and the monsters will be killed. It's cathartic in a way you wouldn't get from real life as there isn't anyone like the Punisher out there though most of us wish there was.
What makes Garth Ennis' stories work is the focus on the characters, not Frank Castle, not painting the baddies as 2-dimensional psychos, but telling a compelling, detailed, and well written story with believable characters. The story clicks along at a fast pace and the action is as sick as any of Punisher's best stuff. The artwork is tremendous as has been consistent throughout this series, full credit to Leo Fernandez for knocking it out of the park in every issue.
Another high point in this underrated character's series and another notch in Garth Ennis' belt for a tremendous ride of a book. Great stuff, highly recommended though very dark.
