In Melissa Broder’s astonishingly profound new novel, a woman arrives alone at a Best Western seeking respite from an emptiness that plagues her. She has fled to the California high desert to escape a cloud of sorrow—for both her father in the ICU and a husband whose illness is worsening.

What the motel provides, however, is not peace but a path discovered on a nearby hike. Out along the sun-scorched trail, the narrator encounters a towering cactus whose size and shape mean it should not exist in California. Yet the cactus is there, with a gash through its side that beckons like a familiar door. So she enters it.

What awaits her inside this mystical succulent sets her on a journey at once desolate and rich, hilarious, and poignant. Death Valley is Melissa Broder at her most imaginative and universal.
