Ada and her father, touched by the power to heal illness, live on the edge of a village where they help sick locals--or "Cures"--by cracking open their damaged bodies or temporarily burying them in the reviving, dangerous Ground nearby. Ada, a being both more and less than human, is mostly uninterested in the Cures, until she meets a man named Samson. When they strike up an affair, to the displeasure of her father and Samson's widowed, pregnant sister, Ada is torn between her old way of life and new possibilities with her lover--and eventually comes to a decision that will forever change Samson, the town, and the Ground itself.
