An urban fantasy novella from USA Today bestselling author Eileen Wilks’s world of the lupi, where the darkest magic will leave its mark...   FBI Agent Lily Yu is turning twenty-nine—a milestone she’s decidedly ambivalent about. But her birthday celebration is cut short when the naked, heavily tattooed body of a man is found in a Northern California town. The victim was David Pruitt, and years ago, he was close friends with Rule Turner, prince of the lupi.   At first it seems like a bizarre ritual killing, but there’s more than magic afoot: David wasn’t human. And the killer isn’t finished...   Human Nature originally appeared in the anthology Inked.   Includes an excerpt of Eileen Wilks' novel Mind Magic.   Praise for the Novels of the Lupi "Grabs you on the first page and never lets go."—Patricia Briggs, #1 New York Times bestselling author   "Full of intrigue, danger, and romance."—Fresh Fiction   “I remember Eileen Wilks’s characters long after the last page is turned.”—Kay Hooper, New York Times bestselling author
