Killer's Kiss — Keri Arthur

An ancient vampire has returned to Castle Rock, and with her comes an even older evil intent on revenge… After tumultuous events in Canberra forced Lizzie Grace to confront her demons—literal and figurative—she returns to Castle Rock, hoping the stalemate with Aiden O'Connor can finally be resolved. Of course, for that to happen, she first has to talk to the man, and Lizzie is fighting a major case of cowardice. But cowardice holds no weight against the force of evil, and this one has a specific target in mind—Maelle Defour, the vampire Lizzie has an uneasy relationship with. As Aiden steps up to fight for everything he wants—including Lizzie—darkness is unleashed on the reservation. One that can turn those who look at it into stone. But the greatest threat to Lizzie might not be the demon or the vampires creating bloody chaos, but the wild magic itself.  Because the wellspring is out of control, and the only way to stop it is to invoke an ancient ritual. One that might kill the precious child she carries.
