Out on the sun-scorched trail in the California desert, a woman encounters a towering cactus whose size and shape mean it should not exist here. 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. The most profound book yet from the visionary author of "Milk Fed" and "The Pisces".
