Blood Challenge (World of the Lupi, #7)

"Lily Yu and Rule Turner{u2019}s engagement announcement is stirring up ugly passions in the Humans First camp. There{u2019}s hate mail. Death threats. Lily{u2019}s car is vandalized. But professionally, things are going smoothly . . . until a lupus in Tennessee goes on a killing spree. Then Rule's brother, Benedict, catches a lovely intruder--twice. The first time she's sneaking around the home of the leader of Humans First. The second time, she sneaks into Nokolai Clanhome with a mysterious potion. It may not be possible to deal with the rapidly escalating situation the way Lily always has: through the law. Especially when she{u2019}s pulled off the case due to an alleged conflict of interest. Lily{u2019}s loyalties will be stretched to the breaking point when she discovers that the deaths in Tennessee were only the opening skirmish in an all-out war."--Author's website.
