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 sorrowfor 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.
