This cathartic collection of personal essays illuminates what the experience of being alone is like. Some of these stories are heartbreaking, such as Jesmyn Ward's reckoning with the loss of her husband and Dina Nayeri's reflection on immigrating to a foreign country. Others are witty, such as Lev Grossman's rueful tale of heading to the woods alone or Anthony Doerr's struggles with internet addiction. Still others celebrate solitude and the kind of clarity it can bring about, such as Lidia Yuknavitch's sensual look at women and desire.
