In the summer of 1968, 13-year-old Stephen Mills of East Meadow, Long Island, went to UJA-Federation’s Camp Ella Fohs, a coed sleepaway camp in New Milford, Connecticut, run by a charismatic social worker named Dan Farinella. “The first time I saw him I thought he might be Rodney Dangerfield’s Italian twin brother,” Mills writes in his new book, Chosen: A Memoir of Stolen Boyhood. “His dark basset-hound eyes and big lips gave him a perpetual hangdog look.”
