QuoteA new book of documentary photographs, "Shelter," examines a group of gay, lesbian, bisexual and transgender young people living, off and on, at a homeless shelter in Hell's Kitchen — a group for whom growing up could hardly be more difficult. That the book is the product of a 27-year-old photographer who is gay, grew up in poverty and once lived in a homeless shelter himself explains its empathetic tone and morally urgent message.
