In rural Yun Village, herbalist Mrs. Yi lives with her husband in a cottage at the foot of Niulan Mountain, where she gathers herbs to treat the ailments of the villagers by day and studies medicine by night. Sickness and herbs are lovers, she tells her patients, rejoicing when they recover, comforting them when they do not. All the while, she hopes to find a worthy successor to take up her mantle. As curious younger villagers observe Mrs. Yi and begin imitating her work―planting gardens and studying the art of healing―they soon discover that the line dividing life from death is porous, and the mountain is more mysterious than they ever knew.

Drawing on her experiences as a barefoot doctor in her youth, Can Xue returns with a transporting novel that alights in the in-between spaces: between the living and the dead, healer and sick, nature and us.
