If you lived in Portland in 2004, you remember it: The discovery that, for years, a father and daughter had been living in Forest Park in an undetected campsite. They were eventually found and housed by the authorities, but soon disappeared again. The story inspired a novel, My Abandonment, written by Reed College creative writing professor Peter Rock, and that book has been adapted into a compassionate, graceful movie by Winter’s Bone director Debra Granik.
