Blood And Salt by Kim Liggett
Determined to find her mother when she disappears, Ash follows her to Quivara, Kansas, the spiritual commune she escaped long ago. But something sinister and ancient waits among the rustling cornstalks of this village lost to time. Her mother is nowhere to be found, but Ash is plagued by memories of her ancestor, Katia, which harken back to the town's history of unrequited love, murder, alchemy, and immortality. Charming traditions give way to a string of deaths. And Ash feels herself drawn to Dane, a mysterious, forbidden boy with secrets of his own. As the community prepares for a ceremony five hundred years in the making, Ash fights to save her mother, her lover, and herself. She must discover the truth about Quivara before it's too late. Before she's all in-blood and salt.
