Holy mackerel. Just started this, but what a story. Freakin creepy.
Update: This is just an amazing heart wrenching memoir. The adults are all psychotic but drawn so effectively that you see the generational damage as it's passed down. One of the most troubling scenes is the grandmother washing the young narrator's hands. Intense and disturbing and haunting.
The end feels a bit rushed in comparison to the leisurely beginning. That's really my only complaint. The afterword is quietly devastating as well, partly for additional depth added to the story and partly for the author's sympathy for people who treated him so horrifically.
