Every once in a while, a book comes along that feels so definitive, so necessary, that not only do you want to tell everyone to read it now, but you also find yourself wanting to go back in time and tell your younger self that you will one day get to read something that will make your life make sense. Melissa Febos’s fierce nonfiction collection, Girlhood, might just be that book. Febos is one of our most passionate and profound essayists.
