[Karin]

Allie's husband is killed in a tragic accident not all that long after she loses her business thanks to him. Joseph is still suffering PTSD from his years in Viet Nam when he rescues a young mother and her two children. On his way back from taking them to her brother, he stops by his home town area the night of Allie's husband's accident. They were childhood friends, so he stays to see if he can help her. This is a complex story of grief, family, PTSD, modern slavery (the mother and her children) and a number of other things that weave together well.
