Blood and Salt: Kim Liggett

This was an intense mystical book for teens. A girl, Ash and her twin brother, Rhy, are raised by their mother, who is slightly scared from being raised by a cult. She practices rituals for "Katia" who she believes to be a dead ancestor. One day the mother disappears and the children drive to a place in Kansas where the cult is suppose to thrive. All that is there is a corn field. I think the book is supposed to build on the "children of the corn" creepyiness. There is a car lot by the field where they stop and the owner tells the siblings that all the cars in the lot were from people who never returned from entering the corn. Ash talks to a boy that disappears into the corn, then she and her brother follow him. They find an entire community that seems a little unhinged hidden in corn field, waiting for the return of this Katia. Evidently this ancestor could live forever and made a pact with the "dark forces", she just needed a "vessel" to return to life. The entire story everyone thinks Ash and Rhy's mother is the vessel, but it ends up being Ash herself. Ash's mom returns to save her from being used by Katia, and "Coronado" who bound himself to Katia centuries before, takes Dane, a boy fell in love with, as his vessel. Then the story abruptly stops...begging for a sequel.
