Mr. Big Empty. Hollow Folk, #1

Vie Eliot arrives in the small town of Vehpese, Wyoming with little more than the clothes-and scars-on his back. Determined to make a new life for himself after escaping his abusive mother, he finds that living with his estranged father brings its own problems. Then Samantha Oates, the girl with blue hair, goes missing, and Vie might be the only one who can find her. His ability to read emotions and gain insight into other people's darkest secrets makes him the perfect investigator, with only one small problem: he wants nothing to do with his gift.
When the killer begins contacting Vie through a series of strange cards, though, Vie is forced to hone his ability, because Samantha was not the killer's only target. And, as Vie learns, he is not the only psychic in town.
